The page contains multiple canonical formats. Stylesheet.

Is it possible to fix this problem with this stylesheet as I have on my templates? This seems to apply to a stylesheet and I have never had to deal with this before..

The page with URL "https://californiaschooloflaw.com/tmp/c ... 14e0a8.css" can also be accessed by using URL "https://californiaschooloflaw.com/tmp/c ... 5dffda.css".
Search engines identify unique pages by using URLs. When a single page can be accessed by using any one of multiple URLs, a search engine assumes that there are multiple unique pages. Use a single URL to reference a page to prevent dilution of page relevance. You can prevent dilution by following a standard URL format.

If they are both active, then it is because there is something different in the files.

You have a href base of / and no canonical links, the amount of links for stylesheets are not anything google/search engines worry about...
