You can create a new scene by right clicking the left most part of your scene (having a triangle and three dash), click add new scene.This worked for me but to be honest i think it is best for mr.creator to fix this issue which seems to be the SCP-049 (Classic) being blank instead of being a scene.

@Stranger You can create a new scene yourself and drag VR (SCP) from SCP-049 folder to the scene i believe. Then you can name the scene and drag that scene to the folder to save the scene.
