New Header Image not displaying

Hi All,

Having a problem on my site – thtc.co.uk – I’ve uploaded a new image for my header, but its not rendering on the site. Instead I have the previous header, which is fine but is a little thin when viewing on mobile.

However, I can see the new header I uploaded in the ‘Customization’ view – see below screenshots

I’ve tried flushing my cache, disabled plugins to see if any clashes were causing this and had a look in the header.php to no avail. It’s late and I’m guessing I’ve simply made a noob error, but would be grateful for any advice.

Cheers
