I'm seeing 4 ZBT-2 devices instead of my normal 2

Configuration

Hi,

I'm unexpectedly seeing 4 ZBT-2 devices in de hardware overview, instead of my normal 2 (Thread and Zigbee). It doesn't seem to break anything, but I'm curious to know why.
In the system device list there are only 2: ACM0 and ACM1, so that's correct.

Any hints on why this could be happening or how to troubleshoot it?
I might be overlooking the obvious.

Thanks,

Rudi

I guess the answer show in here. Where are the beta updates coming from?

Yep, reported a few times in the release thread 2026.5: We're on the same frequency now 📡 - #250 by celkins.

IIRC fix should be coming out tomorrow with the 2026.5.2 hotfix, but don't take my word for it.

Ouch!

I'll improve on my search for existing cases.

Looks like it was fixed with yesterday's 2026.5.2 release
