Copyright & Mobile Nav

Hi Team,

first a big thank you for providing a free version of this beautiful theme.
For my startup that helps a lot!

Now I have two bugs I can’t seem to fix and hope you can push me in the right direction:

1. Copyright text won’t update
I have added a name in the section: Footer Copyright > Copyright text and assumed it would then show up in the footer next to the “? 2017 · ” However, it does not. The spot stays blank, neither in preview nor on the actual site any changes. Saved and published, deleted, saved aso. nothing.
Any idea how I can fix this?

2. Sub heading is off on mobile
If you open the site on a mobile phone, the site name will show top left, the hamburger icon top right and then the sub heading will show in the second row. All with no background color.
Now, on a larger screen (Xperia X) the navigation will set itself, all neatly in one line with a white background and stay that way while scrolling up and down, as soon as you start scrolling.
On smaller screens (Galaxy SIII mini) the sub heading will stay off.
Is there a way to fix this?

Your advice would be much apprecitaed.
Thanks
