F-Series BMW UDS, DTC clear receives Positive response but dash light remains on

Original Project

I'm working on the ability to reset codes on the fly via permanently connected CAN hardware on PT1/PT2. By logging with BimmerLink and doing a reset procedure, I replicated their broadcast request and get a positive result from all modules, yet the light does not turn off. Is there a separate message request that needs to occur for this? Log of the reset exchange attached.
