Bloody Harvest Challenges not progressing

There seems to be an issue with challenge progression within the bloody harvest. Specifically, killing the haunted enemies out in Pandora (I killed a haunted El Dragon jr. and still see 0/0), and the cryo weapon kills within the heck hole.

I am playing on Mayhem 3. I will try this again with Mayhem off tonight and see if that is part of the problem.
