I had a SmartDocs method template .hbr file that I want to use as the default for all new SmartDocs models. I went to Admin>Configuration>SmartDocs and successfully uploaded the file and saved the configuration, then flushed all caches. When I add a new SmartDocs model, I get a warning saying "Custom model template could not be loaded. Standard model template is being used instead."
I am able to update the method templates for individual SmartDocs models after they are created, but it would be much more convenient to set once an apply to all new models.
