Default Buffer Retainer Issue

I am loving my M&P 15. But the last two times cleaning it after being at the range, I have found my buffer retainer and the small spring below out of position. It has been in my lower receiver near the trigger assembly. Full disclosure time, I did recently install a MAGPUL ASAP (Ambidextrous Sling Attachment Point). As part of this install, I had to remove the buffer tube, spring, and castle nut. And yes, the buffer retainer issue only started after I installed the ASAP. Sooooo, what did I screw up and how do I keep the retainer from popping out again?
