Thanks for the testing. I’m rolling out v3.7 to the beta channel now so you should be able to test on Chrome too - Beta testing the Kee browser extension.
Chrome extension store seems to have changed something in the past few months so the beta publish has failed but hopefully it won’t take me too long to work out which new hoops Google require me to jump through.
As for the incorrect form fields being filled in, we should already be taking account of form field visibility so if everything about those fields is otherwise identical, I’d expect the visible fields to be the ones that get filled in. Perhaps there are some different field names or ids which you can configure on the form fields inside your KeePass entry?
