if i reload my pristine ammo clip the ammo i load disappears and a red "<3" message appears.

It does not matter where the ammo comes from and it does not matter if its 30 or 60 rounds.
If i empty a coupled mag with 45 rounds 2 stacks come out. one is 15 another 45.

Here is a video illustrating the issue : http://youtu.be/G8P8TnSxSIs
