Aftermarket mags are tricky things. Some work and some don't. Sounds like you just happened to get some that don't.
The only thing I can suggest is comparing them carefully, side-by-side with known good mags. Look at the feed lips, the front contour in front of the feed lips, the follower, and the magazine catch slot. If you see significant differences in one particular area, see if you can "tweak" the bad mags with hand tools (only if you're confident in your ability to do so) to match the good mags. As-is, they're not working, so the worst that would happen is that they keep "not working".
I suspect it's the feed lips either being too wide, too narrow, or the wrong contour. Without seeing them I couldn't be sure.
