Hi ur35f,
yes - and this problem is already fixed for the next build - but I don´t know when we will get around to publishing it because we have some other fixes for it that we want to include.
For now please pretend that it the panel is INOP - it is possible to fly with this according to the MEL (I have actually done so in real life once, you have to confirm the position of the slats "visually").
Cheers, Jan
