Fix Related Post Typo

I noticed a typo associated with the plugins (seems to apply to all standard templates).

No matter how many related posts you chose to display, it uses the term “Related Post” (singular).

(You can see a new example on your Swift Theme: https://ampforwp.com/demo/amp-pagebuilder/what-shakespeare-can-teach-you-about-review/amp/)

How can I make sure this changes to “Related Posts” if I choose to display more than one?

(Also – just in general – I would love a guide on where to edit all the aspects of the plugin frontend, where to insert ads, etc)
