Always assume you're the one doing something wrong, you really haven't provided enough information to know precisely every little correction that needs to be made. I also can't tell for sure if you're adding the format in after the fact or if it's included with the template drawing prior to the template's use. Keep in mind that there are model based parameters and drawing parameters, and perhaps even with the format, I know you can add a parameter and value to a format. You have to keep in mind that having the same parameter name in more than one of them will cause an issue, so if some clod added a parameter to a model that is or should be a drawing parameter, it needs to be resolved. One of the main causes for that type of thing happening to your parameters in the format, is if it doesn't exist in the model, so a good current and singular model template is also required.
