Can't portal after killing map boss on Creek

In Creek, once you kill the map boss you can not portal out while in the area. As shown below, the portal button incorrectly shows there's an active boss fight even though he has been dead for a few minutes.

This has happened to me 3 separate times on this map.

The fix is simply to walk out of the boss area and then portal, but this is still a minor bug that should be addressed.
