For the second time this game I have won a battle, but the computer doesn't give me the victory

earlier, I beat an AI random event, he fled, but on the main map, he still held the province and I lost my men/leaders

now, I had a leader wind rided to another province, he killed most of the defenders, and the others fled, and yet the enemy still controls the province and my leader is nowhere to be found, (he has stealth as well).
the main board shows a battle took place and I watched it 3 times, and the enemy definitely fled and it said they routed and my man was still persuing when the film ended,
yet he is gone and they still have the province

anyone have any ideas? is this a bug or am I missing something?
