Probably cause you've been upgrading factory or airstrip, then donated before retraining. Bug's been a while.

Yes, While upgrading factory, airstrip or barracks you can't retrain the troops. Also, if you're upgrading mercenary or castle you can't retrain General or mercenaries thru video or VIP retrain.
