I'm reviewing your details and will reply shortly.
Offhand these symptoms point to a microprocessor glitch in the Bose, which in some cases can require repairs. On a user level, the only thing you can try is to unplug the Bose from power for 60 full minutes (to drain all residual current from the system), and then plug it back in.
However, if this does not work, then the unit is in need of service- more specifically the processor has malfunctioned. In this case you would need to contact Bose Service, as they are the only ones that repair their systems:
