Why only one interrupt in two channels ADC sampling

[lbapplem]

Hi experts:

I'm working on STM32U575 evk, using ADC1 including two channels enabe interrupt, attached file is my test project, only one interrupt in the callback function, I don't know why, if I changed the end of conversion selection to end of sequence of conversion, no interrupt triggered, please help to check if anything missing in my project, thanks.
