Saved password is not filling into the password field

Hi,
on some websites the password is not filling into the password field. The username does.
Both input fields do flash as usually, but only the username is filled in the input. So I have to go to the add-on and copy the password manually…
I tried both manual and auto-fill, but it is not filling my password either way. For example the problem is with bank website fio.cz.

I’m using PC and Firefox (and Chrome) add-on. The issue is in both browsers, so I would say there is some incompatibilty of Bitwarden and the website fields, but I used to use Lastpass and the form was always filled OK, so I wouldn’t blame the bank’s form solely.

Is there a way how to check where the problem is or to force the filling into a specific input field of the form?

Thank you
