I am just posting an update to my situation, it was exactly the same as the OP was having. Although, the only difference was that I have two separate enphase inverters for my multiple string system. The main issue in the Tesla Gateway that was throwing off all the numbers was the current transmission sensor. The installer did not correctly hook it up to the right wire (needed to be red) and not all of my solar power was being detected. So I had to run a another wire from the second inverter system (black), and loop it through the current main current transmission sensor in the Tesla gateway. Boom. everything worked fine after that.
