I am having similar issues when trying to enter Poko Kohara Ruins from the travel map screen. And also when trying to reload while I am already inside Poko Kohara Ruins. After a few reloads it seems to fix itself, although once after reloading my main characters portrait changed.

I'm having the same problems, It seems to persist between level transitions, loading previous saves in game, and even when loading saves after exiting to the main menu. But when exiting the game entirely and restarting it fixes itself. I think the music loop occurs when loading a save game while in combat.
