Nextbook 8 (NX785QC8G) confused

I'm so confused why my tablet doesn't have internal sd. All of the memory space is placed as app space. I also can't move apps to sd, is this normal? I ordered this tablet from an online shop and was delivered to me already updated with kitkat 4.4.2, and the System update setting is not available. I saw that this tablet is supposed to have the OTA feature according to its website (nextbookusa). I was able to move apps to sd with my other devices running jb 4.2.2, why can't I do it here? I can access the external sd using stock file explorer but there seems to be no option to move apps. I tried rooting, no luck, i don't want to flash a custom rom just to root, I want pure stock.
