XL Turreted cannon Issue

So i was experimenting with turret building today, and i came across a strange issue where in my turreted cannon did not seem to be receiving power, even though i supplied it with two times the necessary power supply. I originally had a slow, but functioning turret so i thought this was an issue with that, but even when i fixed the slow movement by boosting the reaction wheels, it still did not want to seem to register.

Also, It would be really useful to be able to name new cannon modules, instead it sticks it with default HE TURRETED CANNON.
