multichannel ADC with DMA reads only 0

[JWeij.1]

For my project, i have to read the PA6 and PB0 pins at the same time on my STML082KZT6. These are the ADC_Inch 6 and 8. I have made a code example on STM32CubeMX for the allocations, however the only readings i get are zero.

I have allocated uint32_t VR[2] for data storage,

I initialize the DMA with: HAL_ADC_Start_DMA(&hadc, VR, 2);

In my loop i print the VR[0] and VR[1] bit but those are always 0 even thought the input clearly is not.

Below are my ADC and DMA setups
