LG GGW-H20L with BD-RE DL failing format

I have an LG GGW-H20L drive and I have tried formatting 2 BD-RE DLs (Disc ID: TDKBLD-Wfa-000) and both have failed (one at 99% and one at 49%) using ImgBurn with “Potential ‘WaitImmediateIO’ Deferred Error - (49%, 0/4) - Format Command Failed”. Any known issues with this media and drive? Using FW YL07 which I believe is the latest.

Drive also isn’t formatting MEI-T01-001 discs either! What could the issue be? It works fine with all BD-25 discs I’ve thrown at it.
