Bseed Echo series multiple gang issue

Hey everyone

I recently bought a bunch of Bseed Zigbee switches after being quite happy with a few test examples I bought. Now my current biggest issue can’t be helped here, since the switches are 60 mm and my old ones seem to be 50 mm. So once there is more than 1 switch, they won’t fit the hole in my wall.

Anyway, to the issue that’s HA related. When using the physical switches, all works well, they reflect their status per gang in HA.
But when I tap any of the 2/3 gangs from HA, they all switch simultaneous.
This is annoying since the switches have lights on them, orange is off, white is on. I have a few of these I was going to use as remotes for other switches, so I wanted to synch their states, so all switches show a white light when on. But if I make the automation, it switches on or off all other gangs of the switch.
