Mobile menu 'hamburger' sits on top of feature rather than logo

Hi, on iPhone and Android (Samsung S5) browsers, the ‘hamburger’ sits on top of the feature, below the level of the logo, and is therefore nearly impossible to see. Please see screenshot as example.

I would like this to display on the same level as the logo. Even if it overlaps the logo, that is better than overlapping the feature.

I have tried moving it using CSS as provided by Kika to another user a couple of weeks ago, but that did not move it at all for me.

Can you please help? Thank you!
