Stm32CubeIde Not Configuring PDM Interface Properly ~ Nucleo-H755ZI-Q

[CFran.1]

So the above pic shows SAI_1 configured correctly with 3 Microphone Pairs, on the STM32CubeIde. The pins are appearing in the GPIO.

For this one, I am trying to use 2 Microphone Pairs, but it won't let me change microphone pairs from 3 to 2. This is causing the GPIO to not turn green, they keep saying no mode.

I understand the SAI_1 & SAI_2 D2 pin are connected to the same pin, which means only 5 pairs of microphones can be used at a time with the two PDM interfaces.

My main question is, is this a glitch in the STM32CubeIde? I can easily change the automated code to suite my needs, I just want to make sure its not something else wrong. Thank you for reading this!
