Layout 2021 not recognising updated scenes in Sketchup 2021

I opened Layout and imported scenes from SketchUp 2021. I needed to add new scenes to my SketchUp model and I saved those while updating some other scenes with new information. My Layout model does not recognise the changes (I did save my SketchUp Model consistently) I tried everything but no go, then I tried a work around of saving my SketchUp model with a new name and bingo! the new scenes appeared. I am now on version 3 of my SketchUp model but I don’t think this is how its supposed to work. Any suggestions? Please see my screen shots! The roof framing scene is missing and cross section 2 is not updating to the new framing. SketchUp Scenes in Sketchup Model|690x35
