Somfy ZRTSI level and switch issue

I just added a Somfy ZRTSI controller to my home-assistant. I was able to include everything. I see the screen show up as a level and a switch.

Right now _level shows up as unknown and pressing the up/down arrow doesn’t do anything.

The _switch works just fine. Is there a way I can get home-assistant to use _level as it includes up/down/stop.
