Zigbee switch randomly opens curtains

Hi homeassistant friends,

After an update and restarts because of config changes I ran into an old issue again.
My zigbee button (Livorno Smart button) opens all my aqara curtains without me creating any scripts or scenes in home assistant.
I have had this issue before and this had to do with the fact that the curtains are grouped by default in a Zigbee group (not a group in Home Assistant). I used to fix this by unregistering the curtains to this group.
After a decent amount of googling and searching the forum I cannot find how to do it. Can somebody help me or give me a hint?
I am running the default Zigbee Home Automation on Home Assistant. Which works flawlessly besides this annoying issue.

Thank you in advance!
