Leaking oil cartridges...?

Ok, so the whole oil cartridge deal is new to me. I've been using my Pax for a few years, but just recently started making my own cartridge oil and using the e-cig oil cartridges.
My question is, what's the deal? I bought a 10 pack of "leak proof" wick cartridges and 7 of the 10 leak. When I draw off the pen, I can see air bubbles where the leak is.
What am I doing wrong here?
Should I just purchase a couple CCell cartridges? Are those good with different thicknesses of oil?
