Groups for Aqara Blinds not working

Hi folks,

i have multiple Aqara E1 blinds.
They work fine individually but whenever i put them in a group, either a Zigbee2Mqtt native or HA group, i cannot control them via that group.
I’m currently avoiding the problem by using scenes to set multiple blinds to open/closed but lose the granular functionality that way.

I’d really like to be able to control multiple blinds via one group.
Any idea what i’m doing wrong?
