When opening a storage unit, a basic storage unit for example, u have the options to configure slots. At the bottom it says u can use ctrl + v to copy the slot config. However I don't think it actually copies it.

When I press ctrl + v in the same 'enviroment' it says: "Clipboard contents isn't a valid slot configuration"

Environment (please complete the following information with the version):

• Minecraft: 1.20.1
• Mod Loader: fabric
• TR: 5.8.7

This appears to be working as expect in 1.21.
