Plugin Help MythicDrops Identitifying Issue

Okay, so I'm on this really cool faction server that just added MythicDrops in it today. But there is a problem, the identity tomes don't work, they didn't work on the previous plugin they used either (DiabloDrops) could I get some help as to how to get them working?

This is what I get when I right-click an identity tome, it's more than what would happen with DiabloDrops, but still not working.
