Holes for headliner?

[FLcustom10]

I see the holes for the headliner, but there are two small holes in between the headliner area and the cab light. Those aren't needed for the headliner are they? I'm guessing those are some modification that the previous owner made? Should I fill them in?

Well, you can't actually see the one on the left unless you squint, but you can see the one to the right of the cab light.
