Add More seems to disable custom email template

Hello!

I've got a webform that implements an Add More button. This button deploys up to two additional fieldsets, and correctly captures all this data. Everything about Add More is working great.

However, if someone actually does add one or two additional fieldsets using the Add More button, Webform ignores the custom webform-form.tpl.php email template I've got set up for that form, and simply fires off a completely basic default email.

Any thoughts on what's going on?
