Yes exactly, look at all pics .. manual states not an active fuse slot but there is a fuse there and it controls radio, if battery drains within 3-7 days is that not a parasitic drain ? Battery test good it all aspects.
The circle is not the same place as the fuse. You are not looking at the layout of the box correctly.

GRC. I am confused as to why you are confused... To me, the pix clearly show that an unused fuse position in the panel is now being used, and is wired such that it affects the parasitic drain. The OEM wiring has been modified, and I suspect it is now faulty.

OP, is that really a fuse (what value), or is it a diode? Regardless, if it is a mod to the system, we need to have a full understanding of the mods to have much chance of helping with this beast

I do see they are the same slot but that's not a fuse and we need to know what it is.
