Trados 2021 problem checking out files - Groupshare

I am having a problem where if I am working on a file and get sent another file through groupshare it always tells me I do not have the permission to check it out. The only solution to this is to close the file I am working on and then close and reopen Trados. I can then check-out the file.  So essentially every time I want to open a new file I have to close all the files I am working on and then close and reopen Trados, which is becoming very annoying not to mention affecting my productivity.

Would anyone know why this is happening and how to fix it?
