Issue
"Active!" example colors on https://www.bootstrapcdn.com/bootswatch do not match the example thumbnail image.
Steps
Click a "Try it!" button. For example, United https://www.bootstrapcdn.com/bootswatch/?theme=19

Expected Behavior
Expected the color scheme to match the provided thumbnail image example.
https://bootswatch.com/united/thumbnail.png

Actual Behavior

With some research, it appears that "bg-dark" is used instead of "bg-primary" and possibly other values such as "navbarColor02" instead of "navbarColor01". I'm not entirely sure which of values are needed to match the presented (expected) example image, however some attributes on the "Active!" page do not match the example.
Bootswatch.com (https://bootswatch.com/united/) does not have mis-match issue.
