Words on signs automatically duplicate

Just then I found this glitch on the Xbox version as you can see in the video
It’s a bit frustrating because what if I want to change a sign and it automatically changes to the I wrote on the previous sign
But the bug doesn’t affect PlayStation when I join on the same real, there, it’s perfectly normal

Also I wanted to blur the coordinates and map because I’m in a realm that might become popular and didn’t want to expose my base
