FRDM-KL02Z Power Modes drawing too much current

I have a FRDM-KL02Z board which seems to be drawing a much higher current than stated on the data sheet. I am testing the current across the header J4 on the board, with resistors R27 and R32 removed from the board. In order to remove any issues that may come from my own code I've tested the board using the "power_mode_switch" demo app from the nxp website, and interfacing with the board using UART pins on header J8 instead of via openSDA. The headers J5 and J11 have been disconnected with R31 and R28 also being removed from the board. 

The results I've recorded seem to be much higher than the documentation suggests, especially in the very low power modes. Any suggestions on what I can try in order to bring the current draw down?
