Short description of error
Adding scenes in video editing tab seems to be connected to the scene that is selected in the outliner, in a way that it does not allow that scene to be added (does not appear in the Add pop out). The way around this that works for me, is to create a dummy scene in the outliner and select it, so that the other non-selected scenes can be put into the video editing tracks.
In the help doc:
it is mentioned that adding the scene that is selected is supported, even though it is not recommended to avoid confusion.
