Sorry, but you’re using Diamond, a premium/paid theme not supported in these forums. It’s best to go to the support site where you bought the theme – https://themeforest.net/ – for help with customizations and issues. You paid for support when you bought the theme, so you should contact the people who sold you the theme. They can help with page templates for their theme.

These forums are for free themes available in the WordPress theme directory at https://www.ads-software.com/themes/. See https://codex.www.ads-software.com/Forum_Welcome#Commercial_Products
