Whenever I try to make a new command block, the command block deletes the command when I leave the menu. It was working fine before I updated to 1.19.10, and now it's not. Pre-existing command blocks aren't affected. This bug only appears on my realm, too. 

For example:  I enter the command give @p bread, the command set output appears in chat, but when I enter back into the command block, the command is gone.

Tested on multiple devices, comes up on all of them. Also tested on a new world on the realm, comes up on there. Tested on normal world and not a realm, command block works fine.
