In my HTC One M8 why only 10% app data move to sd card & rest remain on the device storage

[AC Question]

I updated my HTC One M8 to lollipop.....now I move asphalt 8 to my sd card but the problem is only 67 mb move to sd card and rest 1.56 gb left in the device memory. This same case is happening for any apps when I want to move them on SD Card. How can I fix this problem.
