Very Interesting. Just to trouble shoot, I pulled up an old sequence shot on the 5dsr from 7-8 months ago. I started fresh, re-initializing, and I have no problem pulling up the HG Wizard. It seems the difference in the log files is that the sequence shot on the 1dxii isn't able to identify the sequence as having been shot in Manual.
Here's the 5DSR log file:
