I just purchased and downloaded InDesign CS6 from cloud on March 27, 2013. I see the exact strange Presets Colum in my newly purchase Adobe Indesign PDF presets
I use the same program on school computer (two different schools, two different compueters) and all of them have the usual/normal pdf presets.
I am in Canada and my primary language is English, so no, I definitly didnit use Japanese version. However starngely my presets show the same thing as yours does
