Greetings, Contour-pros. Hope we can get a pointer or two about what we might be doing wrong.

We are using Contour on our Umbraco website, and we use a web service as the datasource for one specific form. The form is meant to submit data to the service and have it cleaned, filtered and entered to multiple database tables, and it's working fine. However, we have added a new input field to the web service method. We cannot find any way to update an existing Contour data source to match the revised web service, but when creating a new data source record pointing to the changed service file it renders forms without the new field. This is true using the existing ASMX file, and also after copying it to a new file. The service, called directly, shows the new field and processes it correctly so how do we force Umbraco/Contour to us the right set of fields? Creating a new data source with a new name, pointing to the newly copied/renamed service known to be correctly running, still omits the new field. 

I know this is vague but hopefully someone has some advice that might help. Thanks in advance for any advice or pointers!
