I tried to fix this by replying to my prompt comment (as per the "don't edit prompt comments" rule) --
In the crossover prompts, "Batgirl (comics, 2009-2011)/Magnificent 7 (TV show)" should be "Batgirl (comics, 2009-2011)/The Magnificent Seven (TV show)".
I got the tv show's name wrong when I posted the prompts (because I'm so used to the fandom's shortcut of using the numeral instead of the word for the number).
