Does anyone use the Legrand 067646 switch?

[Riseryn]

Hello,
The Legrand 067646 switch is supposed to be able to be controlled with payload {"position": x} where x goes from 0 closed to 100 open.
mine only responds to position 0 and 100.
when I send a payload, example {"position": 70},
I can hear a click at the switch but nothing happens.
Before seeing if this is a problem with zigbee2mqtt I would like to know if other people have had this problem.
Maybe it's just a problem with my switch.
