ADC connect problem(XMC4500 EV Kit, DAVE4)

Hi~

I started DAVE4 and XMC4500 EV Kit to use five ADC
so composed ADC result programming and circuit
but Although four ADC to analog input(attatched files) of XMC4500 EV Kit connected, discovered the five ADC results in debugging of DAVE4 (from ADC2~ADC6)

How do I solve this problem??

?????
