showing up as a healer on oqueue - help?

i play as a boomkin but i have os healing spec. i don't really use the healing spec that much since i only have dps gear. 

recently when i have used oqueue everyone says i show up as a healer even tho i'm always in dps spec when queueing or joining a group. can i somehow change my setups on oqueue so no one would mistake me as a healer?
