What size batch and how much priming sugar? Did you rack on top of the priming sugar? If not did you stir the beer before bottling?
It could be that you have the sugar unevenly distributed. If that's not the case, and you primed accordingly. I would say just let them sit as is without disturbing them. If you are worried, put them in a big tote with a lid on it.
Lastly, it could be an issue with the bottles or capper. There are different style lips on bottles that could cause a seal issue.
This is grain, which any fool can eat, but for which the Lord intended a more divine means of consumption... Beer!
