When I try to login to website (GAFA AUTODIELY - Prihlásenie) I type incorrect login and after that I type correct login Kee offer me to save old incorrect login from the first try.
I think you’re coming up against the limitation described in Allow user to try different credentials when saving entry on all SPAs · Issue #229 · kee-org/browser-addon · GitHub
We don’t know a way to improve this situation at the moment but welcome contributions if you have a bright idea on how to develop a workaround.
In the mean time, you’ll have to re-login after navigating to a new page (or refreshing/reloading the current page).
Thanks for reporting the issue - it’s helpful to know that this is something that real users are experiencing rather than just the theoretical possibility I wrote about a couple of years back.
