Ventoy Persistence has become discouraging. What have I done wrong.?

I can't see the photo in the link.
You can press F5 in Ventoy boot menu and check the json configuration for persistence and see the result.

Take care about that: 

ventoy  mounted as ext4 on /dev/sdb1 /mnt/gt/ventoy

The ventoy.json should under a ventoy directory, so the full path may be  /mnt/gt/ventoy/ventoy/ventoy.json
