If you are unable to see your page template in the TikShop Admin, this is due to Shopify not having a way to let us know when a new page template has been created.
To resolve this, click "Resync Templates" in the top right corner of the templates button. This should pull in any missing templates from your Shopify Theme.
If you have any issues, please feel free to reach out to our support and we'll be glad to help.
