How can I get Solitude out of war mode?

I'm playing xbox.

I'm a Stormcloak and just completed the quest to take Solitude:

I killed General Tullius, went outside, listened to Ulfric's speech, watched him walk away with the other guy saying "we have a lot to do"

However. Solitude still has the combat music playing whenever I'm there, the icon for Solitude doesn't show up on my map for fast travel, and when I run up there I get a message when I go in the gate that I have to "complete defence of the city". The Blue Palace is locked (though I can break in). The rest of the town is back to normal - no fires, people walking around, etc. How can I get the war situation to end? Should I have talked to Ulfric again after his speech?

Going and speaking to Ulfric in Windhelm made the icon appear again on my map.
