Carnival mission not crediting?

DomoSapien:

I assume I'm stating the obvious here but - make sure you check the number in the top right corner to see if you're receiving completions; 1k damage isn't a lot and the extra damage doesn't roll over to the next completion.

I have a theory that maybe you can only complete either the < or > mission in a single battle. I'm going to take out my Strv and see if I'm getting credit for the long-distance missions.
