Problem with ADC+DMA multiple conversion on STM32G474 - stm32

Question

I want to read 12 channels using DMA in circular mode.
The code is generated using CubeMX and HAL library.
Measures of channels 8-12 are correct and stable but channels 1-7 seems to have changed slots in an array.
The results of these 7 channels
Curve of 1-7 channels ADC
