Several things come to mind.

IF you're using NEW brass, they could have shallow pockets slightly out of spec. Judging by the photo, if that's the case, it's not a problem. Just use a uniform-tool next time you load them to square up any possible nubs, burrs, etc in the bottom before priming.

IF it's not new brass, try running them through again to snug them up where they should be. If you aren't seated all the way, the impact of the firing pin will be partially absorbed by the force seating the primer and you'll get possible light strikes resulting in misfires.
