Problem with some logins on Android

I have a login that works on desktop Chrome but won’t work on any Android browsers that I’ve tried (though I think it used to), so I wonder if it’s a setting I have incorrect. It’s a login with masked name and password, available here: https://ssb1.une.edu:4443/pls/prod/twbkwbis.P_WWWLogin

Is there a way to get autofill to work here? Every time I try autofill populates both fields with the same string. Thanks.
