Disappearing devices

I’m running 20.511. I noticed they came back with different names, appended a 1 to end I think. I renamed them back and changed their IDs back to what they should be, did a reload and browser refresh and the indoor module didn’t come back. I think I may have messed up when I assigned the IDs. I changed the ID of the module to something different and now they are both back. Not sure why the humidity sensors created new devices and got new IDs?
