Search Widget Ruins Page

Hello,

Heres how my page looks normally:
https://www.traveltogrow.com/

Then when I add the search widget to my page it makes all the layout go super screwy like this:

I’ve tried another search widget with a similar result… but only when I input the optional title (the part that says Search Site):
https://farm3.static.flickr.com/2786/4020563307_df48a48d10.jpg

if I leave the title out its fine, but it looks silly without the title.

Ive tried adding a bunch of the other widgets and none of them mess up the site… any idea why the search is different, why would it break it?

thanks for any help.
