Logo not showing in Microsoft Edge

Hi,
I’ve created a new website using education base theme. I was talking to my client on the phone and she claimed two things using MS Edge:

1. The logo is not showing at all in the upper LH corner, it’s just white space.
2. When she clicks on a menu item, it stays expanded even after going to the page she clicked on and even going back to the home page…it does not seem to collapse.

I don’t have win 10 or Edge so I cannot confirm this, but she was telling me exactly what she was seeing. Is this a known issue and more importantly, is there a fix so I can roll this site out?

The page I’m having trouble with is http://www.steerurite.nz

Thank you!
Steph
