Can not see my passwords on password manager

I used trezor password manager way back in 2016 to save a couple of passwords. Yet when I log in there is not a single password there. I kind of need that password.

I used dropbox to log in and I still have the old dropbox files for trezor.

Yet when I log in not a single password shows up. Also I cannot upload the .pswd file to the manager.

I also have .mtdt files for trezor from way back. I assume they are for the old trezor suite.

I would love to get my password back, yet the password manager does not list it.
