STM32F0 Reading multiple adc channels using DMA issue

Hi everyone and thanks for the  help in advance

I'm trying to read 4 channels of ADC using stm32f043 MCU and get the results on DMA interrupt, the problem I'm having is that I can only get accurate and fix results from one channel and although the signal is steady, the reading on all other channels are bouncing and changing constantly , I have tried to decouple the line using different capacitors and also I have taken the VSSA and VDDA from the hardware design file from ST.

how can I get steady readings from all my ADC channels?

again thanks in advanced
