Why do some episodes of on demand titles never show up?


I have been watching the current season of Project Runway on Bravo on demand ( Bravo is one of my pick 5), and it has already once completely left out one episode, but now the last two episodes that used to say upcoming just disappeared and never showed as watchable. It’s frustrating to watch a whole season of something I am paying for and then be denied episodes. What’s going on?
