Locked up my trigger - Armaspec 45 Degree Short Throw Ambidextrous Safety Selector

As a test, I installed my Schmidt 2-stage trigger and did a test trigger pull with no safety selector installed. Worked just fine, however as soon as I install this safety selector. It’s as if the selector did not allow the trigger to travel far enough to initiate the hammer. So, when the selector is on safe - no trigger pull. When the selector is on fire - no trigger pull. Basically made my lower a center piece for display. Not sure if I want to do the hassle of returns or just eat this loss.
