Hi,
If you are in a shared BP database, you might see list of process with the filtering done by other users because filtering in the control room is also shared among users, when someone changes the filtering, it will also be change to others.
Blue Prism Support suggested to create a new BP database, then it will be fixed. It worked for me.
So i created a release for all processes and objects of my current BP database, exported it into a bprelease and imported it back to the new BP database i just created.
Then the issue is fixed.
