PA6 is always biased with 3.3v with OPAMP2 enabled on NUCLEO-L496ZG. WHY?

I'm trying to use both internal op-amps to sample analog inputs with ADC1 and ADC2. When the op-amps are setup using CubeMX (latest version), 3.3v stays present on PA6 input. PA0 works as expected. Both ADCs sample correctly but the waveform input through OPAMP2 is biased up.

I lifted pin 42 (PA6) and the pin reads 3.3 vdc with NOTHING CONNECTED to it. It's clearly a setup problem!

What is the procedure to enable both OPAMPS using CubeMX?

I've tried everything on 2 different boards.
