Typically … 5 bullets …
Use process of elimination on one item (if all items use similar bullets)
Keep 4 bullets - remove one and save to see if it corrects.
If it doesn’t, add that bullet back in and remove a different one and save to see if it corrects.
Repeat process until you find the problem bullet.
Once you find the problem bullet, remove that one from all listings using it (starting with the problem 7).
After you have the bullet isolated, then you can try to figure out what the trigger is.
