Maurosh,

Here's the solution, but it's not a quick one.

Delete one of your models, export the rest, and re-import it.
Keep doing this until it works okay.

Start with the large, black roomdivider, and you will get more furniture in your exported file, but not everything.

Keep trying until you find the next culprit. My guess is, they will be DAE models you found in Google Warehouse.

Happy hunting!
