Cloud-based terminology oddities

Strange things happen when I try to work with cloud-based termbases in a cloud project.

First, the terms that are in a termbase are not recognised and are not displayed neither in Term Recognition nor in Termbase Search.

When I try to look at the settings, I can see that the termbases are checked in the 'Used' column but what is really strange I cannot close the Cloud-based Terminology Settings window with the OK button - even if I do not change anything - I get message "Only one termbase can be set as default". I get the same even if there is only one termbase in the project.

What could be the reason of all these oddities?

Thank you!
