custom aspect ratio in development menu

[DGM]

I input a custom aspect ration as 13.0 x 7.0 by mistake. Now i will not allow me to input the correct 7.0x13.0 or "delete" the mistake of 13x7. ow can I delete the "custom" aspect ratio inputs?

You're right, you can't change it to go "the other way", but you don't need to. Hit the 'x' key while in crop, and the crop box will change from portrait to landscape or vice versa.
