Issues importing Revit 18.3 model into UE4.25 through Datasmith


I am a regular user of Revit but fairly new to Unreal Engine.

I am following an official Unreal Engine course on importing assets into UE via Datasmith.Course link is as follow:

I am able to import the meshes, however when modifying the .uassets settings, the dialogue box does not have a Pipeline, ScenePreview, AssetPreview, Operation and Details windows, but instead, only have a toolbar and detail window.

Can anyone advise if i missed a step?

Kind regards,
