Yes. First thing I checked. I am using the same settings as the previous drawing that this worked on. And on this drawing, SOME of the dimensions come out iso,... some come out ortho. I've noticed, however, that if you show a dimension with that setting turned off... erase it, and turn the setting on, it will NOT revert to iso. Once you've shown it, you seem to be pooched on that part. My solution seems to be.... delete this assembly and start over with new parts that have never had the dimensions shown. PTC... Work on your 2D drawing side!
