No option to postpone match for international call ups

[The J-Man]

Does anyone know why the option to postpone a match because of international call-ups is only available sometimes? It's completely ruined my season. I'm in the Spanish second division, earlier in the season I was allowed to postpone matches because of international call-ups, but on the final day of the season, in a match that I must win, I'm expected to play with my star goalkeeper and my star forward away playing for their countries. I do have a back-up but he's injured, but that shouldn't matter anyway, I shouldn't be forced to play while my players are away with their countries. It's cost me the title, the other team scored from their only shot, which I'm pretty sure my main keeper would have saved. I've spent so many hours working my way through the season just to lose out through no fault of my own.

Post in the bugs forum and share the save so they can look.
