I upgraded all of our company sites to the latest 5.4.2.2 a few weeks ago, and one of the sites seems to have not updated all the way. The Dashboard still has the old naming convention. Any ideas what might have happened to this site? I believe they were all on 5.4.0.5 previously.

Everything seems to still function correctly on the site, just the menu names are off, but I'm not sure if there might be other issues. This site does take forever to load. exploretours.com is the site in question.

Thanks for any insight.

Attached is a comparison of what the menu does look like (left), and what it should look like (right).
