Hump in vinyl sheet flooring

In one of my rooms I am seeing a couple of areas with humps where the plywood subfloor may not have totally been level or even. If I feel that area I can feel the ridge of the higher and lower sheet of plywood. My question is how do I fix that to get rid of said hump? It falls very close to a transition so I'm sure I'll mess that up doing this. Everything seems to bring out a new problem.

The subfloor should have been leveled and smoothed before the vinyl was put in. They should have placed a 1/4" underlayment down before they installed the vinyl and skimmed smooth all the transitions.

How long has the floor been down?

You would need to remove the vinyl to fix what's under it.

Like Joe said, the vinyl will need to be removed. Is it glued down or the loose lay stuff?

Vinyl is incredibly good at telegraphing the imperfections of the subfloor beneath it. As said, you need to fix that and then re-lay the vinyl.
