How come I don't have Raw Recording dimensions W x H people are using?

Hi I am using magic lantern raw on my 5D Mark 3. People are using 1920 x 818 for 24fps, but do not see the 818 to choose from in the height section of raw recording. .Closest number is 840 Also I do not see 1728 x 458 to select for 60fps. Instead closest numbers are 1600 x 480. Do you think I have an old build or am I skipping a step here???
