Galaxy Tab A 10.1" 2016 with S Pen

[AC Question]

I have a 16 gig Galaxy Tab A with S Pen (the 10.1" 2016 version) and I'm wondering if anyone else has noticed the storage numbers being off. I have 2.5 gigs free = however, I also have a 64 gigabyte SD card... with 850 megs of content on it. Thing is... there's more than 850 megs of content on it since I moved EVERYTHING I COULD to the SD card and that includes apps that says there's over 1 gig of data on them. I'm perplexed.

Is my Tab counting ALL the data as internal even though it's clearly not there or is there just something going on that's not clear.
