Raid a bossbar is duplicated in villages without a raid and remains after the actual raid ends

I started a raid in a village, left that village before the raid ended, and entered a couple other different villages.  A duplicate raid bossbar was created in each subsequent village I entered, yet no raid spawned near any of those villages.

After the actual raid ended, I returned to the other villages and the raid bossbar remains with the health unchanged from when I first entered.
