Are movies from earlier this year being reissued at AMC since it's award season?

I recently got A-List and have been spending a lot of time looking at upcoming showtimes and even searching up films that are far ahead to the point they don't typically show up at the home page or won't have a poster with the title. I came across both these pages for Sing Sing and Dune Part II and was wondering if anyone knew if there was any validity behind this random January 17th date for both.
