Can anybody help with a Wix editing problem?

[Sue]

Just one part of our new (ish)  website is not properly copying over to the mobile version (text colour of some subheadings) in just one section.

I can't find a way to edit just the subheadings for mobile - I can change the font colour for all the text in the section, but not change it just for the sub headings.

There's no problem with editing the subheadings in the  desktop version, but the editing isn't copying across. It has done it fine in every other part of the website.

Can anyone help? I'm not very familiar with Wix.

The specific section is the top part of this page:

The subheadings should be in orange on the mobile version, as they are in the headings  further down the page 🙄
