No line breaks for heading at lowest breakpoint

Hello,

I am working on making my design responsive, but I’m having trouble with one heading not inserting a line break when it goes down to the vertical mobile break point. I’d appreciate if someone could take a look and let me know what’s gone wrong with it. I’ve adjusted two other pages without this problem, and there are also headings on the same page that are going on to two lines like normal. I’ve checked everything I can think of, but this is my first Webflow site so I’m sure I’m just overlooking something obvious!

Below is the share link. The problem is the “WHAT WE DO” heading at the top of the “Services” page.’
