Sorry for the late reply, however the plugin is fine, those bugs you mentioned are not caused by ItemEdit
The hide issue does not exist on spigot, it only exists on paper and paper forks and it's not something a plugin can override/fix

Similar issues and inconsistency are/were also caused by ProtocolSupport/ViaBackward when a player 1.20.4- connects to a server 1.20.6+
Again, not my fault, not something i can fix
Thanks for being "good" and keeping me motivated to provide a free service with one star review over bugs not caused by me and unfixable by my plugin
Truth is that those answers and help to walkaround those limitations were already provided on discord in support channels
