Fuses/Exterior Lights Question

I have a couple questions.

First, I’m having some trouble getting the exterior lights- the porch light and the floodlight up by the batteries to work. The porch light worked when I went and looked at it before I bought the camper, but now I can’t get it to work. Neither the switch on the bottom of the light or the light switch right inside the door do anything. The light up front I have never saw it on. I checked both bulbs and both look good. I haven’t got the multimeter out yet to see if I’m getting power to the sockets yet.

Is there something I’m missing here?

The 2nd question- the picture I have attached is of my fuse panel. The red light is lined up for the fuse location marked for the fridge. There’s no fuse here and the fridge still works. I’m wondering if there has been a mislabel and this fuse is for exterior lights and that’s the issue or if it’s totally unrelated.

I’m going to get some fuses tomorrow and test that slot out, but in the meantime any help would be appreciated.

Thanks.
