Trying to Change "Featured Letters" on Northfield

So I’m having an issue changing “Featured Letters” to “Featured Photographs” on the carousel that came with the Northfield theme.
The theme already had Featured Letters as a default upon upload and I can’t find anywhere to change it on the backend.

Here’s the page in question.

I feel like if I could access the HTML then I could change it, but I cannot access the HTML either. Please help

As far as I can see, the default text there for the Northfield theme is “Featured Items.” Maybe the one you have was previously customized to use “Letters” instead?

This is written into the theme in the theme’s index.php file (themes/northfield/index.php).

Thank you!! I found it immediately and changed it
