Here are how the pins are supposed to be connected: imaging flipping your RPi down, with the male pins facing the female pins on OSPi, and that the Ethernet jack is pointing to the right, then your RPi’s 2×13 pins plug into exactly the first (from left) 2×13 pins on OSPi. In other words, with the RPi facing down, the RPi pins and OSPi pins align on the left.
