Darkrp Double Job Problem

My coder was messing around with putting a NPC on my server, but it didn’t work, so he erased the NPC coding. The only problem is now for 3 days we have had double jobs.
There are doubles of every job that we have on my Darkrp server, anyone know what he did wrong or how to fix it?
Sorry for not much information, I don’t exactly know what he did.

Run a Find In Files search for “AddExtraTeam” in your whole gamemode directory.

lol he’s bad if he can’t add npcs
