When you open the itemjoin menu the "modify" tab works but everything else doesnt work
pls fix

Hi, I need more information to be able to resolve this issue.

On my end, everything is working as intended.

Can you please provide;
1.) Your Spigot version.
2.) Your ItemJoin version found by typing /itemjoin
3.) Pastebin.com links of both your config.yml and items.yml.

Once I get those I will work to resolve the issue you are having.

EDIT: Marking this as fixed as some users were able to replicate this issue so I patched it in a snapshot.

Remember to remove your old ItemJoin.jar file

This bug has been officially fixed in the release of ItemJoin v5.2.2.
