I confirm, odd things happens when extracting the both images by 7zip., it seems that there is some bug in 7zip or the images are corrupted in some way or there is some conflict between 7zip and the images.
I extracted both images by 7zip but at the end of the both extractions I got:
"Warning: there are some data after the end of the payload data" for Rescue image and
"Unexpected end of data" for EFI Debug image.
However, I followed your workarounds and both image are booting this way.
