For some reason, Google decided that only first party apps are able to be saved to the SD card in 4.4 KitKat. I root and use Link2SD to get around it and move all apps except system apps. SDfix does the same thing, but I haven’t tested it. Unfortunately, without rooting your device, you aren’t going to be able to get around the limitation on moving apps. I’m not sure why Google has such an aversion to SD cards, but they certainly seem to.
