Weird issue with device group

I’ve created a device group for my outdoor PIRs, that’s cool when one triggers the device group entity triggers and I can trigger automations to trigger another device group for my outdoor lights. Thats all working well.

But I noticed tonight that when I add each individual outdoor PIR as an entity card on the dashboard, they all show as “triggered 2 minutes ago” even if ONE device triggers. This is weird because I am choosing the entity of the actual PIR and not the device group entity. Not sure where the connection is here.

So, even if the Pool PIR doesn’t trigger but the lower deck PIR triggers, they all show as “Trigger x minutes ago”

Any ideas? I don’t even know where to start haha.
