Shutter FGRM-222 does not accept % in scenes anymore

[BartFF 0]

Hello

I am a HCL user since nearly two years now.
Recently, I have upgraded to v4 (the major one, not a beta)

Every morning, I use scenes in order to open my shutters ((FGRM-222)) in two simple steps :

    - At the given time, open 15% of the shutter (open the shutter holes actually)
    - 3 minutes later, open it 100%

It used to work perfectly for months.
Since the v4 upgrade, it is impossible to obtain a partial opening.
It is only widely open or closed, the percentage does not work.

When I use the HCL interface, I can manually perform partial openings and closings with no issue.
I have also tried using Magic Scenes, and it works, but unfortunately, Magic Scenes are too limited for my need.

I have tried to create brand new blocs scenes as well, instead of using my old ones, and the result is similar.

Have you already faced this kind of issue ? Ideas ? Advices ?
Would a box factory reset help ? I am ready to redo everything if needed.

Thanks in advance for your feedback and have a nice day !!
