Players RP going into the negative

For some reason I have a players RP going into the negative. Actually 3 players... One is at -113, one at -90, and one at -136. Not really sure why... I would think that if the player didn't have any RP to go below 0 that it would just stay at 0 instead of going negative? Not really sure what plugin could be causing it to go below 0, but if there is a way to add a check that basically sets the players balance to 0 if it goes negative, that would be awesome.

Any update to this issue?
