RefindPlus v0.12.0.AN no longer scanning OS X volumes

[Steve]

I recently upgraded RefindPlus from v.0.12.0.AL to v.0.12.0.AN and now it is no longer scanning my OSX volume as it was before. The author of RefindPlus suggested I post my question here. I do not know if this is because of a bug of somekind or mis configuration on my part, though I have tried to be very careful about using the settings I had before, maybe I am missing something.

details:

The main OSX volume in question is a Mojave boot volume, called "Boot". If clear the NVRAM, it will boot normally becuase it is in the first drive bay. In previous version of RefindPlus, it also showed up in the Refind boot screen, but now there is no sign of it. When I use the DBG version of BOOTx64.efi, the log shows no mention of it either. Its not being detected.

My RefindPlus EFI configuration is on another drive that doesn't have any bootable volumes, called "Scratch".

The EFI partition on "Boot" has only /EFI/APPLE/EXTENSIONS/Firemware.scap

Here is the override.conf file:
