Power consumption on STM32L476RG NUCLEO in various power modes

I am testing the demo code given in the directory STM32Cube\Repository\STM32Cube_FW_L4_V1.14.0\Projects\NUCLEO-L476RG\Examples\PWR for CubeMx. I am testing the code PWR_ModesSelection and am recording the current values across J6 IDD which I'll be writing down below.

For SHUTDOWN, I'm getting a reading of 3.84 mA.

For RUN Range 1, 80MHz with FLASH ART on, I'm getting 14.08 mA.

According to the document, an4621, (https://www.st.com/content/ccc/resource/technical/document/application_note/9e/9b/ca/a3/92/5d/44/ff/DM00148033.pdf/files/DM00148033.pdf/jcr:content/translations/en.DM00148033.pdf)

power consumption without RTC should be 0.33uA. Why am I seeing such a high current value? Is there a drain due to the components on the board?
