Can't see all files in internal memory

I finally got my MT7-L09 running on MM by flashing TWRP backup images posted by others, but I'M still having a few problems with it.
1. When I USB connect my phone to my computer(s) it only shows 4GB of internal memory in the device, it should be 16GB. I only see the basic folders, in Internal storage......alarms, DCIM, HWThemes, Notifications, etc....14 folder total....it's like I can't see the root, it's like LP is still installed and my internal memory somehow got partitioned.
2. WIFI doesn't work......it stays grayed out and doesn't see any networks.
3. Bluetooth doesn't work.

I currently have TWRP installed, so if you know of any fixes, let me know if I have to flash the stock recovery.

Any help would be appreciated.

Thanks.
