Bug report

I'm using version: 4.2.1
I'm on Minecraft: 1.21.1
I'm running: Paper

Seen results:
As title suggests

Expected results:
the database should remove the original sign

How to reproduce:

1. create a receiver sign (using test for this example)
2. right click on the sign and change the channel name to something else (in this case test2)
3. type command to activate the original channel (/wr activate test)
4. type command to activate the second channel (/wr activate test2)
5. see both commands activate the sign at same location
