Catch-22... FixupAppleEfiImages key and schema error

Just updated to 0.9.6 OpenCore, I have managed to rid myself of 5 other missing Schema error messages (by removing the keys from config). ocvalidate from 0.9.6 says no issues, but one error/warning flashes up before OpenCore boot screen, Missing Schema for FixupAppleEfiImages... I added the key from sample config.plist, but the Missing Schema error remains.

If I remove the key, I get a missing Key message :-|

Any thoughts or ideas would be greatly appreciated. thx.
