Elementor – Single Page

Hello All,

I need some help with creating a template page.
I have been currently following a tutorial online how to set up a filter/search engine for a online course website idea I have.

All going well until I get to the part where I need to set up a ‘Single’ template and then choose the ‘Post type’.
Problem is that there is no ‘Post Type’ drop down menu to choose. Really stuck and I hope someone can help?

I have attached a screenshot to my website and the link has been provided above to give you more of an idea.

Kindest Regards,

Mark
