I am pretty sure your mission is the planet with that name, not the station because it only says the planet's name in the mission I assume.
It says Iltari Station and I'm there but its not completed or anything
That is quite unusual. I assume you have the necessary amount of copper ore in your cargo. I will investigate if there is an issue which prioritizes docking over completion of missions. It's the only thing I can imagine causing it.
I see, thank you for helping me with it though, I do appreciate it a lot
