"Remove Only" map tab is empty; but, it has not been deleted, even after being empty 3 days.

Hey there! This is currently a Known Issue. Sorry for any inconvenience this might have caused you!

I'm really sorry this issue hasn't been resolved yet, and completely understand your frustration! I too have a few Map tabs that just refuse to go quietly into the dark night.

Unfortunately we don't have an ETA for when these tabs might be removed automatically upon being emptied, but the team is aware of the issue and are working on it.

In the meantime, please accept this gif by way of apology as launch gets ever closer.
