I have two different projects newly created and migrated some levels from older but different UE 5.4 projects. In both 5.5 projects I created a terrain and placed a material on it. In project 1 everything seems good, all submenus are there (see attachment 1) In project 2 were many submenus missing (attachment 2).
The only difference between the two projects: I created project 1 with the "Third person" - Games template and project 2 with the "blank" - Film/Video & Live Events template.
In attachment 3 you found the DashSceneData from both projects.
