Hello,

I saw the screenshots you attached.

The dashboard says to activate the plugin because the plugin is one of the recommended ones.

1) If you have activated a one-page builder plugin then you need to make sure that the other one is deactivated.

And make sure that the one which is activated is also selected from Theme Settings >> General.

Then the imported demo will be using that page builder that is activated.

2) And for the colors and settings not working please make sure that you have set both the addresses the same under Settings >> General.

Then clear the cache and check back.

3) And for the icons please provide the URL of the website to check it myself and help you out accordingly.

Best Regards.
