How to fix text alignment and unexpected yellow line in Fetch theme?

[Bonneta]

The first one is that the text "¡Síguenos!" is too close to the text to its left. There is no margin, and visually, it affects the UI design of the website.

The second thing is that there is a yellow line that appeared out of nowhere in the mobile view. These two problems don't affect the web view.

The third problem is that the Policies text is aligned to the left and it should be centered. 

First goes the copyright.

Below are all the policies.

Please review and help correct them. Thank you!
