STM32 MCUs Products

I'm using 4 ADC channels and sending the data to a DMA buffer. The data from the different channels are interfering with each other and i'm not sure why. The goal is to read from PA0, PA1, PA4, and PA5 at the same time. so i may going about it wrong.

my data for this looks like the following without giving inputPA0 PA1 PA4 PA50 250 216 190I expect this PA0 PA1 PA4 PA50 0 0 0and when i start giving channel PA0 data wit...
