Welcome to the Lumion forum.
So anyway, what version are you using?
Shadows are generated in real-time as shadowmaps. Those maps are displayed in Build Mode which is the mode you have taken a screencapture from.
If you have used the Shadow Effect and changed the shadow properties you need to see the scene with that effect applied, so click on the Build with Effects button in Photo Mode or Video Mode.
Going directly from either mode to Build Mode (and not through BWE) does not show the effects, but only the Build Mode default settings. Those settings are determined based on the need for real-time performance.
