STM32CubeMX: STM32L431RC: ADC IN14 has incorrect conflict message

With my pin assignments ADC IN14 shows a conflict with PB0. Which is incorrect according to the datasheet. The conflict should be with PC5. IN15 also shows a conflict with PB0 which is correct.

The warning on IN14 is saying you can't enable differential mode because IN15/PB0 is occupied. If there were a conflict with PC5, you wouldn't be able to enable single-ended mode either. No bug here.

I suggest adding some words to the message that indicates that the conflict is with the differential mode.
