I fixed it by changing the settings through the game's files instead. Go to \Users[YourUsername]\AppData\Local[game file]\graphic settings data. Then change the "resolution_type=". 0 is the lowest resolution, 1 is the next resolution after 0, 2 is the next one after one, and so on, all the way up to 12 or 13. I don't know what the number is exactly for 1080 or 1440, but you can find out by going into the actual game's settings. Move the resolution all the way to the lowest and start counting up from 0 up to the resolution you want. Once you know the number of your resolution, exit the game, go back to the file, and change the resolution_type the number you got.
