Finally the first IKEA cover in Deconz - but it's not updating the position?

I finally got my IKEA Kadrilj in Deconz, and because of that in HA.
It reacts on the buttons, and the slider, but it does not update the position of the cover in HA, so the ‘up’ button is just greyed out?

No offense, but what is your question?

A question of anybody that knows what is wrong.
But I got it solved, I needed to read the attributes a few times, and then powercycle the cover.
