Those two fuses are just a couple of fuses Grampy has laying there in the opening. That space/opening is actually the holding spot for the fuse removal tool/clip. Also, fuse position 8 is showing a fuse when actually, on the R3T at least, it is not used nor does it have any connection terminals in that spot.
I'm correcting this for the Roadster...fuse position 8 is fused for Instrument illumination and position lights
