B-WL5M-SUBG1 Current Consumption is Too High

Hello,

I'm working with B-WL5M-SUBG1 hardware for experiencing STM32WL5MOCH6U. 

I ran the application from Repository\STM32Cube_FW_WL_V1.3.1\Projects\B-WL5M-SUBG1\Applications\Sigfox

I got current of about 2.3mA in standby mode instead of  less than 1uA as specified in the datasheet and I discovered that the 5V_PWR LED(LD4 Green) was ON.

I broke the SB14 to prevent the 5V_PWR LED from turning on:

Current down to 900uA-950uA band with this move.

After that I applied this post's recommendations. 

Current down to 875uA-810uA band.

But I unfortinatelly I'm still far away from 1uA. Anyone has soluion?
