Seems to be if you have IB ornaments on IB gear it for some reason stops it from registering. I just took my IB ornaments off of my IB gear and it started progressing on the triumph.

This is correct I don't know why it is correct but this is the way

I think it has to do with the game not knowing how to handle 5+ pieces of IB gear. They give you one so you can still run an exotic so if you have 5 pieces on the game boosts it to six. So my assumption is the IB ornaments on top of IB gear counts as two. So once you get to five pieces of equipped gear the game might be resetting that number to zero in the background.
