Collections have disappeared, but I can see the workspace has collections in overview page

We are not able to see our collections under our team workspace anymore, but when I sign in using the web interface, and select the overview for the workspace there is a summary on the side which does say there are collections in this workspace. Where id usually see my collections there is only an option to Create Collection as tho its an empty workspace.

Is there something which has happened to hide these collections?

On attempting to create a new collection, i can see the count on the overview page increase for that workspace, but soon after Im not able to see this collection anymore either.

Thanks!
