Since your first 2 pictures indicate that the car thinks it is doing AC charging
(like at home with a UMC, HPWC, or other EVSE), there has been a failure to
communicate properly on the Pilot Control line from the Supercharger to
the car.
Normally, the Pilot is a -12v to +12v square wave signal which is used
to communicate a maximum charging rate (AC amps) to the main
charger in the car.
A Supercharger distinguishes itself by indicating a desire for digital
communication by using a 5% duty cycle, which is lower than the
normal minimum of about 10% used in AC charging. Then, the car
begins using the pilot line as a 33.3k bit per second (slow) one-sided
CAN "bus" to converse with the Supercharger.
Usually, the Pilot line goes to the main charger in the car,
and I suspect that it has to recognize the "digital data mode"
request, and begin translating the single-side CAN messages
to "real" CAN messages, that probably get handled by the BMS
computer module in the battery.
Apparently this conversation failed in some way, because the car
did not recognize that it was connected to a Supercharger.

The Charging Complete message probably means Charging Stopped (for
some reason), not necessarily "filled" (to your selected limit).
The reason was probably that it failed to do any proper charging
for some extended period of time.
