Fires on safe?!?! - OpticsPlanet Exclusive RISE Armament RA-434 High Performance Trigger

I bought this trigger just a while ago, and it is an absolutely FANTASTIC trigger. It's like snapping an icecicle when you pull the trigger, it's quite incredible feeling for the price. HOWEVER, I tried to fire it while on safe and it actually does fire. It fires now with a 4# pull on safe. I've put my milspec safety back in, still happens. I put my old milspec trigger in, no such issue. Now this may be an adjustment issue with the trigger itself, but the only thing I know is that it fires on safe, and I don't want it on my firearm.
