The trip reset as normally but the distance is not calculated correctly.If you top up with fuel it will reset to zero automatically - a feature that can be disabled in the menus. I suspect you might know this already though.
I have a turbo build and 1700cc injectors. Unfortunately fuel gauge will never be accurate.I would see if it continues to under-read, then if it does, I would disable the auto-reset in the menus to see if it "thinks" you're topping up the fuel when you're not. I assume the fuel gauge sender is the detection device for the refuel so perhaps that is a bit sensitive or not reading correctly so keep an eye on the accuracy of the fuel gauge to see if that seems to read as it should (ie consistently falling and not rising without new fuel being added).
EcuTek has the same problem. We have the same tuner
