This problem started happening with one of our users as well.  We are using Desktop Premier Plus 2021.  It's like the auto-fill is working but you can't see it.  If you leave the account and amount blank it will let you save and close and the payable will be entered.  The problem is you can't see what you're posting unless you go back into the entry to view it.  We tried turning off auto-fill but that doesn't work.  The weird thing is it is only happening on one of our computers no matter who is logged in.  We even tried adding a new user.  Other computers don't have the problem.
