motion track problem.

Hello, all.
I’m new to motion tracking and i’ve tried to make a motion track, but i have a problem.
I have 7 marks that work (the triangle in the middle not), but i can’t click on setup tracking scene.
Do you guys know what i have to do to get the marks in a scene.
I’ve put a screenshot of blender.
I only marked and didn’t do anything to the scene it self (nothing changed on camera’s or other setings).
Ty, already.
