I made several changes to an entry on my Mac copy of 1Pass, deleted them, and found that somehow it was showing them even in the trash. I deleted the trash and that fixed that problem on the Mac. On my iPhone I have discovered the same problem with those entries, even though the trash is empty there. I click on a name or PW field in Safari on iPhone and it brings up 5 possible entries. See attached photo.
If I do a search in 1Pass on iPhone, it only shows the correct entry as shown in second photo.
