Problem with changing names in anvil

For some reason, me and my mates have discoverd a bug that makes it so you cant change the name of a name tag or a block ( like a shulker box ) or any tool on our new 1.18 realm

this is very anyoing as one would find but it is getting to the point where some of our pets/mob are despawnning and is leading to an unfortunate experience

Thats the main bug that im worring about the other is that we cant wright on signs 

but thats all from me 

thanks for all of your hard work
