On Paper 1.19, I can create frames but not remove them

[OBattler]

What steps will reproduce the problem?

1. Create a frame
2. Remove it

What were you expecting to happen? What happened instead?

I was expecting it to be removed fine so I can then proceed to clean-up the item frames. Instead, the removal fails with an error message relating to ItemEntity.

What version of the plugin are you using? Type /version <Plugin Name>

The latest (4.13.5.-SNAPSHOT).

What Spigot version are you using? Type /version

Paper 1.19.

What plugins are you using? Type /plugins

Multiverse-Core, Multiverse-Inventory, Lift, Chairs, Stargate, Worldedit.

Do you have an error log? Use pastebin.com. If you're not sure, upload your whole server log

Would have to reproduce it again but I can do so if needed.

Did your client crash? Upload errors in .minecraft/logs/latest.log as well

The client did not crash.

Additional information? (Are you using Bungeecord? Did it work in previous versions? etc.)

I am not using Bungeecord. This issue did not occur on Paper 1.18.2 with the same versions of AnimatedFrames, MapManager, and PacketListenerApi.
