It is not a bug, and that has been clearly stated. If you wanted this to be moved to the suggestions forum, then fine, but if not, I don't see a reason for this to be open.
I personally see that you played POCT against a bot, and made no tactical changes from BO/M2M during the finals even after the other team came to fruition. If you cannot beat someone who just created their team days prior, I don't think promotion is deserved.
