I created a page template and exported it, to import it on the projects in which I need to use it. However, it happens to me that when I apply it I don’t find it as I set it, but it deletes the title and then the image I uploaded in the imported page template doesn’t appear.
Importing individual Page Templates works between Page Template Sets. If you want to export to a file and into another Project File, you need to export the Page Template Set.
