Error in the styling of the single Post

I made a post type by the jet engine, after that I created a listing for these post types to appear in a grid on the home screen, then I made a single post template for these post types, but when I click on one of these post types I am redirected to a page without styling and without content, different from the single post I created. I correctly configured the listing button that when pressed it accesses the POST URL, but I don’t know where wordpress is getting this post url from since it’s a page that I didn’t create, the correct thing would be for it to take the single post
