COVER ATTRIBUTE NOT WORKING

[NevenBra]

I am running the latest Home Assistant version on Home Assistant Blue - Home Assistant 2022.8.7, Supervisor 2022.08.5, Operating System 8.5, Frontend 20220802.0.
I have a KNX integration for the cover entities and I am not able to assigne a different attribute for the tilt position for the slider. So, the slider perfectly shows the vertical position cover with invert (KNX 0 open -100 % closed cover), however I cannot assign to slider different attribute about tilt position.
So, one button slider is about the vertical position, and another one for the tilt position...
