How to stop the animation at the last scene, and not the first scene


I am trying to export an animation of the solar course of a building during the day. For that I create one scene in the beginning of the day and one scene at the end. I chose like 15 seconds of transition between the scenes and no stop on the scenes.

When I export the animation, I have during the first 15 seconds the solar course I expected to see but there is 15 more seconds and it represents the transition between scene 2 to scene 1.

Thank you in advance !

In the Export Options panel untick Loop to starting scene.

Thank you for your help !
