Hi Mahtab, 🙂

The “Find People Near You” and “Let’s Make Dating More Human & More Simple” section of our demos are made with WordPress navigation menus. To edit this menu, you have to select the “Feature – homepage” menu in Dashboard > Appearance > Menus.

You can change the text displayed by editing the description. If the description text area isn’t visible, please review your screen options, at the top right of your screen. More on this in the following video tutorial:

In the case you want to change the colors or the icons for this menu, please read the following topic:

Concerning the underline, my best guess is that your issue might probably caused by some extra code snippet as we don’t encounter this issue with our demos.

Could you deactivate all plugins that have not been installed with your theme during its setup and all existing custom snippets please? And then, could you confirm me that the issue is still persisting please?

Please also make sure that you have the latest theme version and that all recommended plugins are up-to-date. Finally, you could also consider clearing all activated caching system as well as your browser cache before investigating any further.

Best,
