SEO issues

Hello, i have a kinda wierd question. I have a annual subscription to Envato elements, and i noticed that when i’m using one of the HTML templates for my websites, Google doesen’t see them.
in one particular instance, even searching on Google site:mydomain, there a no results. All of the content isnt copied, it was written for that website, i inserted the meta description and keywords, Google search console. I can find the issue. Any ideas why this occurs? Thanks
