Image instead of text title I can do but menu item dissappears

I am trying to figure out how to have an image as a page title without also needing to have a text title. On this page for example: https://www.adamleesumner.com/books/ I have successfully placed an image including words and because of this I no longer need the text title that is usually added into the box given for this purpose. The problem is that if I delete the text in the title box I mess with the title showing up in the menu. Instead of “books” showing as a menu item it says something like “#no item”.
I am inexperienced with code.
