Mobile menu does not style like full size menu

I love this theme, so thank you!

I’m just having an issue with the mobile version of my client’s site.

The site is https://www.truelifestories.com.au/web

On mobile, the following is happening:
– Social icons not displaying in header
– Menu button isn’t centered
– Menu colours are not obeying css styles set in theme options panel

Appreciate any help on this one. Thanks
