Changing the render distance in the options.txt file puts it to the lowest one indicated in the game itself.

Hi. I'm having a big problem making the render distance's number of chunks (through an external text editor) a number not possible to be selected in the game's settings. Whenever I do it, the game always selects the lowest possible option instead of the number I typed in the text editor I mentioned above. The only possible options in the game's settings are 8, 12, 16, 20, and 24 chunks. Please fix this great issue. Thank you.
