Autorecord used to work, now it only records about half of the shows with the keyword in the title

My DVR used to record every show with "Dodgers" in the title. It did this without fail for several months. Suddenly this has stopped. When I go to the "smart search," I can search for Dodgers and a whole list of programs shows up, but when I push the button for "keyword Dodgers," less than half of these shows are actually available for autorecord. This is NOT how this used to work.

What happened? It used to work, now it doesn't. Is it time to go back to TiVo?
