Random line on single page

Hi there,

Could anyone tell me what might be causing this random line on one of my pages?

Here is the link: https://glasses.net84.net/
Theme is: Delicate

It’s only on the ‘Our Services’ section of the site. It’s the same line that encases the navigational menu.

Kind of random. I hope somebody can help. It just showed up out of no where after a bunch of page updates so I couldn’t pinpoint when it began to do this.

I will mention that I have edited the page.php file I believe it was…to remove the title of each page, but I added it back in, so this might be a clue.

Thanks in advance!
