Blooming Field Boss Arena - Unable to Leave

Hi,

I'm on Blooming Field map and I'm locked in the arena. The area where the beast master is typically at had a rare monster in its place (map boss was not an added modifier to this location).

After killing the rare, I went to leave and the door has been closed behind locking me in the arena. On the other side you can see the checkpoint and Arena entry available to click, but unable to leave.
