Doesn’t cycle - Ruger Magazine MINI-30 7.62X39 10 Round

Purchased the Mini 30 magazine in 5,10, & 20 round for the Ruger American Gen 2 in 7.62X39 as this was what was supposed to be the correct one. Haven’t shot any of them, but the 10 round magazine doesn’t cycle the ammo. The first round out chambers difficulty and the second round is pushed into the magazine at a 180 degree angle. Every time I tried it. When looking closely the magazine is clearly built different than the 20 round one.
