Objects misplaced

When I reloaded my fbx file, most of the objects were misplaced. Please, you need to fix this bug. It took me so long to rearrange everything.

Hi,

Did you use D5 Converter? Could you please recall the steps?

I dont prefer d5 converter, i import as fbx

Got this problem with light source in Revit. See attached screen shot. I use Revit 2021, and the D5 converter. Also, got two fixtures but only one light source.
