Bug in Slicer - not showing selection correctly

By the way, there seems to be a difference of how much text is typed-into the search field. If I don't type the full category name (project name in this case) so that there are at least two options left to choose from - then main field picks the selcetion without any issues and shows in the main box. 

But when the typed text becomes long and accurate enough to match only one single value of all the project names, then the main box stops reacting to the selection inside the slicer and just shows "All".
