I want to send books to a address but the addresses dont show up

I dont have any crash report.

Please complete the following information:

• Minecraft Version: 1.16.5
• Mod Version: MrCrayfishs-Furniture-Mod-1.16.5.jar

Same goes for 1.18.2 and 1.19.2: mailboxes don't show up in the post box. I use Forge 43.1.2 with other mods.

Also having the same issue, redownloaded the mod and everything. On a server and no one else is having the same issue.

It's also not working for me on 1.19.2 :(
