When Creating a brand new Simulation template, CRTL+L does not move the sun, anyone know why?

Sorry for the newb question here but im relatively new to this

Im following a tutorial on creating a terrain import, and the first part of it says to move the sun with CTRL+L to shade the mountains, yet when trying to do this, the wheel comes up but its locked and does not move

Another tutorial said to go into the blueprint mode and disconnect the Update Sun Function from the automatic time and day procedure generated by the template, I did that but still the sun is locked

Any ideas how to unlock this so its moveable in any direction like this:

Again sorry for the newb question but im not sure what to do, ive been looking around the forums and internet and none of the answers I find work.

Figured pros might now why its not behaving as it should
