make sure “automatically route buttons” is unchecked, then route each video thumbnail button back onto itself(all 4 route points), and then delete any Sub picture highlight Layers that the video buttons may have, now change the number of your text buttons to #1,2,3 and route them from one to the other,change the video buttons to #4,5,6, . Just make sure that none of the routing points of the text buttons route to the video buttons.this is one workaround for it
