Faustus icon won't go away

Hello, I'm encountering a quite simple bug : Faustus has no earnings left to collect but the icon is still here. Even logging out and logging back in didn't fix the issue.

EDIT : Also, one of my merchant tabs has become remove only for some reason (it's not written, but I cannot put items in it)

EDIT 2 : After removing all items in said bugged tab and relogging, the icon is gone (but I still can't use the tab)
