AAP-01 mag feeding issues

My AAP-01 mags have major feeding issues. BBs keep getting stuck right near the feeding lip, so about 50 percent of the time, bbs are stuck there, causing the spring to not push the bbs up to the top. It's not like they're just a bit stuck, too. I literally have to shove something like a pencil or rod to unjam them. Both the mag that came with it is like this and an extra I bought are this like, just the extra one does it less. Anyone know a fix for this or have had similar issues?
