Bad Hashrate on Nanominer?

Hey Ravens. Just wanted to see if anyone else is getting really bad hashrates on nanominer. For a test case. My RX580 gets a rock solid 13MH/s on Teamredminer while I'm looking at 11MH/s on nanominer. If this is some settings or something I'd like to figure it out because nanominer is the only miner that supports my Firepro S9150's mining KawPow.

Cheers
