Hi,
>> I can't see these hatches. I don't know why
Open the "1ST FLOOR.dwg", activate modelspace and zoom extents. Then press <CTRL><A> to select all objects ... and be surprised ...
If you don't see geometry outside your "project area" then please start command _ABOUT and show me a screenshot of that dialog.
This is what I see doing the above steps ... (in AutoCAD 2022 and 2023 you see more, but in 2021 you see object selection at areas you don't think objects are placed)

Also there exist geometry on the DEFPOINTS layer, and even worse these are annotative blocks.
If you want objects to not plot, then create a new layer which has the property "No-Plot", but do not (never) use the DEFPOINTS layer, this is reserved for AutoCAD internal use.
And if you want objects to not be plotted, why then making them annotative?
