I recently converted a project to the pro version from the standard version. When I tried to update the PCB from the schematic, the update was going to remove many of the 3d models from the standard components (basic parts in the JLCPCB site). I can't find anything to update these components so that the 3d models aren't removed. I tried "Design/Update Project Library" but this action is irreversible and I have no idea what it does. The documentation seems to be out of date and all the pictures of menus are in Chinese. Please advise how to handle this situation, and consider updating the documentation.
