The thing to understand with Google is that its algorythm will display what it thinks benefits the user, not what you want. Sometimes that aligns and sometimes it doesn’t. If you can see the text you entered in code then its there. If it is different in the Google SERPS then Google changed it. This has nothing to do with Webflow.
Adding to @webdev 's advice, it looks as though Google simply has not re-indexed your site yet. Check your Google search console where you submitted it, and you’ll be able to see when it was last crawled.
