One page not showing in second language

The Polylang plugin is working just fine in English but in Spanish, the “About” or “Sobre” page does not show up. The “Sobre” in Spanish shows up if you click on the “Sobre” link at the top of the page, but it does not show up when you scroll down.

I am sure this is something simple, but I cannot figure it out. Any and all help / suggestions appreciated.

The Polylang plugin is awesome except for this tiny glitch.

Many thanks for your help.
