Well, that's odd, then. Updated my subscription before posting this. I just purged my uBO cache, downloaded updates again, and they are still showing. I checked my browser notifications just to be sure, and they are empty. It is definitely coming through that website in one way or another since they do not appear anywhere else. Again, it doesn't always happen, but when it does, you have to wait just a few seconds.
Life is what you make of it, even at the most difficult of times.
