the same problem as
#488

Does the correct value show when you run /lp user <user> info, under 'current prefix'?

Temporary permissions are handled in exactly the same way as permanent prefixes in the meta system, so this is most likely an issue with Essentials or the way you have LP setup.

Your chat formatting plugin seems to be applying formats based upon a users primary group.

As you might've noticed, in both cases, "Current prefix" shows the correct value, but the users primary groups are different.

To fix this, you can either:

1. Switch the chat plugin to just pull the prefix from LuckPerms - it's not doing this at the moment.

or

2. Change the way primary groups are calculated. (I'd change it to either parents-by-weight or all-parents-by-weight. You then need to make sure each of your groups have an appropriate weight assigned to them)

Just to clarify, this is absolutely not an Essentials issue.

You've just configured the plugin (EssentialsChat in this case) incorrectly. I gave two solutions above.
