11-pin connector power

Good day everyone!
I try to power up Xadow Duino by GSM+BLE board over 11-pin xadow bus. And failed. Maybe i’m not good in plugging little stripes in tight places…
When I try to place bus in socket deeper I short Vbat pin to GND :frowning:
maybe it’s not a good idea - to place GND and power in the neighboring contacts.
GSM+BLE xadow socket is fried now, but board looks good.
finally my question: How to connect modules properly? Hi-res photo, manual or good advice.
