Only the logo on the login screen has received a new name, the logo after login has exactly the same name as before:

If you are seeing a different logo reference, I would guess that you may have uploaded another company logo in either a group setting or client setting.
The problem was due to the deactivated company, which is no longer used. There was no logo there. After I uploaded the logo in the deactivated company, it is now also displayed in the dashboard for the customer, although it is a customer of the active company.
So the question is, why are settings of the wrong company used and how can I fix this?
