1) Maybe you could try to press: 'c'

And then run 'ls'
and tell us what Grub sees.

2) As an alternative you can try my former SG2D 2.02s9 release which had
implemented another search algorithm:
https://sourceforge.net/projects/supergrub2/files/2.02s9/super_grub2_disk_2.02s9/super_grub2_disk_hybrid_2.02s9.iso/download

I'm a bit out of clues without being able to debug this more.
