Meeting name is "Microsoft Teams" on join screen (Quite urgent)

Meetings created by a user through a shared mailbox does not display the correct meeting name on the join screen (see image below)

The meeting name is correct if I view it in my calendar, but not on join screen.
However, the intent is that the meeting link is part of a big sheet of multiple invite links. 
So this is a last check to see that you are joining the correct meeting amongst several others.

The same meeting can have the correct name for the organizer of the meeting, but other meetings does not display the correct name.

The meeting options looks like they should, the only change that was made was that everyone could bypass the lobby and the meetings has not changed name since they were created.

What can we do?
