Can't override author.php template

I have copied author.php from plugins/classifieds/ui-front/general/author.php into my active theme and edited it to match my theme. The problem is it is still using the default author.php in plugins/classifieds/ui-front/general/author.php. Why won’t it override it? It worked when I did the same thing for page-classifieds.php.

Any help is appreciated.
