Not sure why it says SKUs updated :1 after changing from automated handling time, all SKUs should be affected.
This new seller fulfilled recommendations page showed only 1 SKU
https ://sellercentral.amazon.com/seller-fulfilled-product/analytics/ref=xx_msfp_dnav_xx#RECOMMENDATIONS
And each and every item I sell needs to be sent the same day it was purchased.
I have set the SKU handling time to 2 days. Each time I go back into that inventory item and click Edit, the handling time is set for 0 days.
I’ve opened up a case for it, had a lot of back and forth with people who don’t know anything, and now the case is listed as “transferred” and that I would be contacted about it. That was over a week ago.
Definitely is an “open a case” issue.
There are two things that we would check.
Things to try
It will be interesting to see if your situation is unique to you or if others have a similar issue.
I believe the answer is that only 1 SKU was impacted: they need a lot of data showing you regularly ship a SKU “early” before they modify the handling time (internally, where you don’t see it). We has only 3 SKUs affected, one of which was the one that flagged the problem for us.
But a lesson that should be learned by every seller that hasn’t been bitten by this yet is that you could be bitten by it tomorrow. If one later order is a potential issue for your metrics, you’ll need to regularly check this until sellers stop being surprised by this malfeasance.
My handling time under Shipping Settings should apply to all SKU’s, not just one. They modified my Automated Handling Time setting by turning the automation on. Without my knowledge, without notice or warning. I had it set to off.
I did recently ship one of the SKU they showed me, but have been shipping others too. I have quite a few SKUs going out regularly.
Yes, we all need to check that daily as @papy advised.
I assume you mean this?
I can’t change that time, unless there is a setting somewhere else in the system to do it? It’s not editable on that screen.
I can turn it on and I can turn it off, but there is no Save ability on that screen. I think it auto saves when you change the status cause there is a little floating notification bar that appears.
I have not done those before, and I am a little trepidatious about it. I also don’t know what catagory most of my items are classified in. I sell new books, on existing listings (I have never created a listing), but some are video games, some are books, some seem to be under board games, and I have no idea how to even look into that. 
Oh, and thank you kindly for your advice!
What page are you on when you see that?
Generally, we set those items here under General Shipping Settings
Same here. But when I click edit, it shows up and it is not editable.
May I ask if your SoA (‘Amazonese’/‘Amazonish’ for “Selling on Amazon”) Account is enrolled in the Professional Selling Plan, or in the Individual?
Been Pro since 2020
OK, then it would seem that that’s not the reason why you can’t access the ‘Edit’ functionality.
May I ask if you can access the Edit Dashboard itself by navigating directly to its default URL linked below (link ‘broken’ for Discourse display)?
I can’t edit that time, either, but it hasn’t caused me any problems.
We are qualified for Seller Fulfilled Prime (not using it but qualified) so maybe we see and can set things differently.
Have you ever been qualified for Seller Fulfilled Prime?
Hmmm.
May I ask if you’re using the default “Migrated” Shipping Template exclusively, or have set up your own ‘customized’ Template(s)?
Perhaps you can specifically request that your case be transferred to the “Amazon Services” team? FBM outside of SFP seems to be covered by this team.
I would try, but being that it is in transferred status, I can’t actually reply to them anymore. I figured it was their way of just burying my ticket in limbo.
Ummmm, dunno. I created the new template, filled it out and saved it. Not sure what migrated templates would be.
