Calendar fill is clumping multiple calendars so you can't turn them on/off individually

[Mulliszl]

1. when I fill my calendars to select which ones I do and don't want, It fills it as a single calendar. listing it in terminal outputs as multiple lines, so I'm assuming its an import issue. I couldn't figure out how to set individual calendars as false in terminal to see if that fixed it.
