Can't get LastBootedVolume to work with EmuVariableUefi.efi

Hi All

Just made up a new x390 iHack. All working great except for this one minor, but bugging issue. I can't get the lastbooted volume and timeout to work. I have several OSX builds + windows so its pretty handy.

Seems to be something to do with EmuVariableUefi.efi. Swapping it out with AptioMemoryFix-64.efi seems to fix the issue but it breaks sleep, which is arguably more important.

Any help would be much appreciated

Heres' my config if that helps:
