As was mentioned the problem was caused by the cached version of the theme files. After every plugin and theme update you need to clear browser cache and site cache if you use cache plugin, CDN or server cache. Sometimes cached versions of the CSS styles or scripts cause error after theme/plugin update. In your case, it’s the double logo.
You can create a staging site (full copy of the existing one) and do updates of the theme and plugins there first. If everything is ok then you’ll be able to update the production site.
