Having trouble the Productize template button

I am having trouble with my nav bar button not adjusting size properly. Im using the Productize template as I’m quite a novice with Webflow. I was adding a blog page and I’m unsure of when the button broke but I wasn’t able to undo the changes far enough back to fix the button. I did not mess with the button at all and the issue persists even if I am to copy the button from the “Style Guide” page.

Hopefully this description helps. Thank you for any help in advance!
