After successfully receiving credits on three of my cards this year for TravelBank purchases, I just received a weird additional credit for $97.99 (and an additionally weird credit/debit) on one of my cards...



This $97.99 credit does not correspond to any charge and my statement currently has a negative balance. Anyone have any idea what this could mean? I have not had anything similar occur on the other two cards I made TravelBank purchases on and my TravelBank balance is still accurate.
