This feature has to be enabled. looks like you inadvertantly disabled it.
Go to a map, bottom left will be the map name with the level, the number of targets hit eg: 5/12, and a question mark in a green box.

Tap the question mark and you should get the area mastery box. Make sure that show missions is enabled.

Hope this helps.
