The weekly challenge for vanguard strikes text does not correspond to the actual challenge in place. The text states that I need to complete vanguard bounties, which haven't counted towards the challenge's progression, which is to complete 3 strikes with the correct elemental subclass (tested it out by switching to the correct subclass, void in this case, and running a quick strike mission). Took this screenshot after my strike test run, which is how I have 1/3 completion. This display error has been happening to me for at least 2 weeks.
