Problem dimming down k8029 with k8006

Hi,
I’m experiencing some issuses with K8029. I hooked it up to my K8006 and reprogrammed the times t1 and t2, this works
fine.
When I switch it to the slow-on/off mode and press the button it starts to dim up but when it reaches maximum intensity it never dims down. Instead, the yellow LED just goes out. For information, the red LED is on during the entire time. I do not know if this is normal.
Could someone please advice on a solution?

Regards

I still need assistance in this matter. A new discovery is that sometimes when it reaches full intensity it starts to flicker and then continues as previously described.
Should I state my issue somewhere else to get support?

edit:
I hate to be pushy but I am at a standstill in my project due to theese issues, is anyone from velleman looking at this?
