Under certain conditions (exactly when is not clear to me), AWB general fixes will add a {{DEFAULTSORT://article title//}} to an article. This is fine, except when the article is a "List of " type. Then, the DEFAULTSORT key should be set to the article title without the "List of " prefix (and the next word may need to be capitalised) - as ordering within a category under L for List is not helpful.
Example: List of Czech Republic–related topics
