Problems moving Performances in Rig Manager

When I use my Kemper live I have created one performance for each song and I then use the Rig Manager to place the songs in the right order to match the set list for the night. Now when I try to do this I cannot move the performances by “click and drag”. They jump back to their current position. I have checked that I have the latest software both on the Kemper and Rig Manager. Any ideas on what the problem could be. I could add that for the next upcoming gig I have had to move the performances on the head using the “arrange function”. When I have done this the Rig Manager seems to be out of sync- when I click on a performance in Rig Manager a different performance is called up.

Thanks Hudiluma. I actaually found the solution in another thread. You had to click on the # (top left corner in the window).
