Help please, mags keep falling out

Hey y’all, I’m having an issue and I don’t know how to fix it. I shot about 500 rounds through my dagger and everything was great. Then I put in an apex trigger and shot another 200 rounds and it was great. Then on my next trip after about 100 rounds pmag magazines started falling out while shooting. Glock mags seemed to work fine. I said whatever, I would rather use Glock mags anyways. Put in another 100 or so rounds with just Glock mags and it was fine. The next trip the Glock mags started falling out, and the pistol was essentially unusable. After contacting psa customer service they sent me a new locking block, mostly because I had read on here that that might be the issue but after installing the new locking block I was having the same issue. Anyone have this issue? Could I have messed something up installing the trigger or do I just have a defective lower?

Also, I’m not hitting the mag release while shooting, I took my time to make sure that wasn’t the case. I also used the upper on my Glock 19 factory frame and it want just fine this morning so it’s not that. Any ideas? Also, if I do replace it do I have to pay a transfer fee again? Thanks fam!
