I want to measure the current when S32K148 in tc10 sleep mode

I used SDK named phy_tja1103_s32k148 and I can see change state via LED of S32K148

then, I tried to measure the current via J19 (I already removed R59) referencing below
https://community.nxp.com/t5/S32K/how-to-the-put-the-S32k148-EVB-into-sleep-mode/td-p/1233592

but the current of wakeup mode is about 49.5mA and the current of sleep mode is about 47.5mA.

I think it's not reasonable data

but when I tried to measure the current with VLPS & HSRUN & RUN mode, I can see reasonable data

 

What is difference between TC10 Sleep mode and VLPS mode?
and How can I get reasonable current data in TC10 sleep/wakeup?
