Tool Assembly reuse?

I need help. I can't get the Tool Assembly Search tool to work. I am in 3dExperience DELMA Shop Floor Machining. Makers License.

There are the files that I manually moved in there and I've tried the "add to library" option after I create it in a different manufacturing cell. Nothing shows up to be selected. I am entering the search with no filtering.

I can see that there are a relation to each file I have added to this library but there is nothing to select. 

Is there a default setting somewhere that is toggled wrong? An error message I get is:

"Impossible to retrieve Library content. The library might no more exist, please refresh the widget or remove from favorites."
