Want to Hide Page Titles

I don’t want the page title text to show up on my sub-pages because I’ve created picture banners on each of the pages that incorporate the title in them. Having the text there makes it duplicative. But if I don’t include a title in the title field of a page, it displays weirdly on the navigation bar of my homepage.

I kind of understand coding, but am not great at it, so am hoping for a pretty simple fix. Any guidance would be greatly appreciated!

Here’s an example of one of my pages: https://thecapitolhil.com/toxic-free-home/
