Hello Ruben! Unfortunately the full purge can cause a little trouble. I suggest only purging directly from the components and styles dialog. Don’t purge tags/layers. Since we aren’t actually applying SketchUp Tags to geometry, ConDoc tags will be purged. They come back when you run a tool, but the levels won’t come back until you run the project setup again. So to fix, just run project setup, LEVEL tags will pop back in! If you don’t have the LEVEL tags there can be strange behavior where all tags and objects are disappearing.
Beware, if you have purged the tags this can mess up scenes previously created by ConDoc… Since the default behavior of “new” SketchUp tags is to be visible in all existing scenes.
We are baking in a fix for this that will allow full purging.
