Thanks!
This is an example of what was happening.

I re-installed sketchup and the plugin without success, I was using SketchUp2019. Yesterday I upgraded my license to SketchUp2020 and the problem was fixed.

If I generate area report, it shows all areas on the plugin screen but if I export to CSV it gives me an error and only shows the information of one of the entities.

How can I fix the mistake?
