Storage space is showing wrong storage space

AC Question

My internal storage space was showing about half full and and sd card showed correct amount of storage. I have many apps moved to sd card and media too. Now suddenly it is saying my internal storage is full and incorrect amount of space available on sd card. I checked my apps and they show they are stored on sd card. How do I fix it so it shows the correct amount of storage on both my internal memory and sd card memory?
