Need Help Identifying page layout

Hello,

I have just inherited a squarespace site for a company I work for and they need me to add a new page, however, when I click on the new page button and it gives me my layout options, none of them match the current pages, I am also unable to duplicate them for quick refactor, I was hoping someone would recognize the "dashed box" icon and could hopefully point me in the right direction as to where to start.

Thanks!

It you provide the site address then I can find out what template it is and know more about the layout options. 

In the meantime  the dotted boxes  looks like the icons for info pages, that are used in the Aviator family of templates, here is some good info about them.

The site is https://www.mototvnetwork.com/

It is a custom template I believe, I just need to figure out a way to duplicate and refactor one of the current pages, I can do it in a text editor if thats easier, just struggling to find any docs that don't lead you in circles.

It does appear to be a custom designed site.
