u/AccordingCatch

Hi all ! I recently installed Vidga on my ceiling (plaster with screw plugs) with the mount it gave me, but I’m seeing a slight gap between the rails and the ceiling (where u can see light seeping at the very top) on the railing on the right, is this normal?

The left one is flushed to the ceiling it’s on, so I’m confused if this is just how it is? Or should I do something about it.
Sorry about the picture
