The standard GP Child theme doesn’t contain any templates, so if they must have been added somehow. There’s a possiblity they have been added by plugin but it’s definitely not something that GP adds there. You will need to examine the child theme directory to see what has been added.
There’s not much we can do.
Log into your server via FTP and check to see what folders are in your Child Theme.
Make sure none of your plugins need them and then remove them.
You sure you haven’t added something for Woo Email templates?
