Ep 12, I think, hasn't and won't be shown yet as it's a crossover episode with NCIS New Orleans.
Ep 11 should be there and may turn up but it's on tomorrow night. You could record it in case the on demand version doesn't materialise.
PS The second part of the crossover episode is also Ep 12 and it won't be shown for another 5 or 6 weeks. I guess they'll be shown back to back then.
