Search Box Not diplaying correctly

Hi,

I have the search box option enabled on my website's menu and everything works fine except on the search page itself...

If you look closely you will see the search box populates on top of the menu instead of covering the menu bar like it should as shown on the various demo websites.

I noticed it only happens in Chrome, safari works good.

I think there is a problem with the plugin "showcase idx" as the only pages that have the issue are the generate press search page itself and the page that is setup with the showcase idx plugin.

Again, this only happens in Chrome.

Can you please help? Perhaps there is a css code that can be added to make the search box display ok in Chrome?

Here are the pages where the problem happens:

https://svpremier.com/real-estate-search/ (showcase idx plugin page)

https://svpremier.com/?s=bayside (generate press search page example)

All other pages work ok as for example the home page to my website does not have the issue:

https://svpremier.com/

Thanks so much for your help!
