Weird duplicate and original page "unlisted"

I made this module and it had a pretty good build up of information on people using it, but I come back to find it "unlisted"
https://www.modulargrid.net/e/other-unknown-clacktronics-mini-speaker-

and in its place is this

https://www.modulargrid.net/e/other-unknown-clacktronics-euro-speaker

why?

There was a duplicate and we unlisted the wrong by accident. I have reverted it.
