Preformatted text clashing with featured image

I’m having an issue with the preformatted text merging/covering up the featured image on my site.

As you can see, on this page it’s fine.

But, on this page, the preformatted text box and the featured image merge.

WordPress have said that:

“Portrait images are displayed aligned to the right within the text. There isn’t a way to force or change that in the theme, so to avoid it, the only way forward would be to use landscape Featured Images only.”

Is there a way to stop preformatted text merging with portrait featured images? Or, if not, a way to force portrait images above text?

Cheers!
