Git won't find Metafiles

This is a weird thing. I'm working with a team and we use Git to share the project. When I push my changes to the project, my Meta files never show as part of the submitted files. Sometimes, when I push my changes, the metafiles register on other users versions of the project.

But sometimes, especially when I create new scripts or prefabs, they get no metafiles.

I know that I have checked the "metafiles shown" option in the Editor menu. So, what am I missing? Why does this happen?
