Can't change background image of top region in Spirit theme

Can't change background image of the very top region in my custom Spirit theme.
There's been some updates recently that may cause this. I updated upfront and two other wpmudev plugins.

My other site running the same theme but I didn't do an update on is working.

Support access is granted for both sites.
Please review these two websites in case you can locate any difference between them.

This has been one of a long list of issues when I update wpmudev plugins or themes. Can I please have a resolution to this issue by 22/4. I was planning a homepage refresh this weekend but due to these issues I have to postpone.
