Problem of menu format

Hi there,
I’m using your plugin myStickymenu on my site https://isavedalife.charity/. As you can see when you visit the site, the menu is showing as a bulleted list vertically on my site.

I had this set to show all on one line, horizontally with no bullets, however within the past few days I noticed this change on my site. I’ve not made any changes to my site, so I’m wondering if there was an update to your plugin and if you might be able to help me get it resolved?
