Qubino Flush Shutter with relay behind it (no load)

I have a Becker sunscreen which is controlled by a Becker transmitter with analogue inputs.
I have added a Qubino Shutter Flush zwave AC in front of it which basically simulates an analogue switch.

I am having an issue with the stop button; this most of the time does not work.
I have set the Qubino to Shutter mode and set the run time with parameter 74; 370=37seconds.

There is no power consumption since the Becker relay is behind it.
Is there any need to calibrate since it basically runs on time now?
I have set 76 ( Motor operation detection) to 0 since the Sunscreen has it’s own limits. Does this disables param. 85? ( Power consumption max delay time) I believe so since setting a position does work now.

It works fine when setting it to 50%, HA will run it for half the time.
But when I press open and stop few seconds later it will keep running open.

2nd the image of the slider is the other way around. When 100% open the slider is fully up instead of fully down.
When fully down it show as closed.

I found some topics regarding parameter 3 and 5 but these are undefined. I can’t find them in the manual as well.

Anyone figured out these issues already?
