Qlink problem

Anyone have the problem of the qlink assignments forgetting their assignments especially on fx . It either forgets it altogether or switches to another effect in the list.
Also noticed on mpc studio the orientation of the qlink suddenly changing, eg. Usually it's vertical for fx but suddenly changed to horizontal.
Also in program edit the LCD suggests both horizontal and vertical control is active. Anyone noticed that.

i nver use the q links..i tried them out for a pitch bend effect and when i rendered the song it didnt even export it right ;(..it just sounded all pitched down instad of a pitch bend
