Ask for target folder and project name when the one is created from template. Edge Animate creates a folder with a template name. That folder name has to be changed almost always to a real one manually. Project name is Untitled-1 for me, probably because I created a tempalte from non-saved project, which is sub-optimal as well. At least create a project from template in temporary storage/memory and it works with regular "New" one before you try to save it.
