Just recently. Maybe 10 days ago. That's about when I really started using Enpass though. Or, at least when I had something going on where I was doing a lot of searching and adding new records. The searching, not finding what I need, then back-spacing is what causes the issue.
MacOS v10.15.7 (Catalina)
Enpass 6.6.0 (772) (Mac App Store)
Firefox v85.0.2 (64-bit)

I don't use any other browsers
