Remove tags in zwave tools

I did have Ghost modules in my Zwave mesh network.
At the latest version off Homey I could remove these by the Remove button at the Zwave tool.
Very Nice, and I’m happy about that.

But I do still have about 5 remove buttons at the Zwave tools list I don’t know why they are there?
These devices don’t have to be removed and they functionate normal?
Is there an explanation about these buttons?

Nobody?

Hahaha
Oke. Your right. They don’t harm
