S32K ADC PAL Conversion groups configuration

Hi,

The project that I am working in needs to convert 15 channels using ADC0 and 3 channels using ADC1.

When I use RTM4.0.2 to configure the ADC modules with ADC_PAL_Configuration, I fails to get the correct converting result if I set one ADC0 conversion group where there are 15 adc0 channels and set one ADC1 conversion group where there are 3 adc1 channels. The results which should appear in the adc_pal_0_result0[] appear in adc_pal_1_result0[]. When I set two ADC0 conversion groups, contain 8 and 7 channels seperately, the conversion results are in line with expectations.

What is the difference between these two configuration?
