CC3000 shut-down mode is drawing far more current than it should

Hi,

We built exactly as per reference design (see below). On holding VBAT_SW_ENB low we expect 5uA as per daasheet but we are getting about 1-6mA and it varies from try to try. SPI_CS is high so that's all disabled.

We've removed modules from PCBs and remaining circuitry takes tiny amount of current.

We've hooked up 2 CC3000 modules with wire to test it by itself. 1.5mA when SPI grounded. 4.5mA with SPI IOs floating all tested at 3V (see photo below).

Any ideas?
