EFI Option missing from installer (Gnome Live Image)

Hi

I've been having some issues with installing from the NEt image so I have downloaded a full gnome image however, when I try to manually partition the drive there is no option for an EFI option in the options within the live installer menu.

I usually have

1GB (EFI)

1GB (EXT2)

rest as encrypted storage EXT 4

Not my first time installing manually so I'm not sure why the netimage is having issues now.
