I'm not sure what you're talking about but Metamask has always been an option for connecting to the site; in fact it's sadly a first-citizen wallet.
From my experience it's Brave that is causing a lot of weird behavior patterns and issues.
Only thing I can tell you is that the UI will query whatever wallet you have connected and use that address as the base for all displays. Make sure the address you took the loan with is the same that's currently connected. Check if there are any errors being displayed in the browser console.
