“London’s Burning” won’t unlock

Hello all,
This is my last achievement in the game. After finding every collectible and weapon I ate everyone and slept and saw the newspaper article for every district going hostile. In the in-game menu it says that I have every district hostile (three of them are at 0-5%, and Pembroke is at 32% for some reason but it shouldn’t matter since it’s below 50%).

However, the tracker still says that 3/4 of them are hostile instead of 4/4 even though I know every one is hostile. This leads me to believe that it’s an issue with the game itself not recognizing or tracking that a district is hostile rather than the achievement itself. Any help would be appreciated.

If you take Pembroke down further does the achievement pop?
