Padlock on playlist movie rides

Hi.
Using Tacx MobApp on Windows 11, opening every playlist at first instant appears on thumb images the green check for the rides already done (and none on the not yet done) but in less than a second on all thumbs appears an orange padlock.

I can open and start each ride without problems, but I cannot see which one I have already done and which one not.

I have the problem on my desktop PC and also on laptop (the one I use for training session), both them with the save version of Windows and Tacx MobApp.
The problem started a month ago, but I wait for some fix..
