That sounds a lot like the rounds aren't sitting in the magazine properly and/or there may be a slight burr on the extractor claw that's stopping the rim from popping up into the bolt face as it's pushed forward.
The CZ is a "controlled round feed" not "Push feed" like a lot of others that don't need the rim to pop up fully onto the bolt face.
I'd say the fix is just some careful study and removing/smoothing a few edges perhaps on the magazine lips and/or behind the extractor claw.
It's got some thinking going here of way back in memory of those in the past that have had a hiccup with a CZ mentioned on many a Forum. For those that persisted I think it was just use of loading many rounds that the hiccups went away.
If it's gone back under warranty then I'd say Winchester will probably just finely remove some burrs and/or smooth some surfaces. If it comes back and there is still an issue I would say that use over a period will solve any remaining problem. They are tight when new and do get a lot better over time. I'd rather have it tight than like a sloppy Remington....
