What is Asana created custom field "priority 1201316773927420"

Thanks for the extra information, @Matthew_Nelson! I’ve gone ahead and escalated this to our product team so we can investigate further. Since this is an Asana created custom field, we cannot remove it completely from the Asana template but we can update the name to show the right one. In the meantime, you can remove the field from the project created from the template by clicking the Customize menu > Edit field > Remove field.
