Since I can't seem to post in the technical support page.....
Every time I'm invited to or try to create a new CWLS it replaces an old CWLS even if I move the old one to a different number.

Eg CWLS named boxes is in the 3rd tab...I'm invited to join Sharks when I accept the new invite boxes disappear and is replaced by sharks. I am still in boxes CWLS I just can't access it.
If I move boxes to the fourth tab and re accept an invite from Sharks it still replaces boxes.
