Default Nvidia Shield Tablet External 2 Internal issue

Hey, everyone! I got a 64GB MicroSD card for my Shield tablet so I can have a lot of space for apps and games. I've tried everything, followed maybe 5 or 6 tutorials to get External 2 Internal working. My tablet was rooted using Towelroot. I have made screenshots of all my settings. I'm still stumped... If there's another way to make apps install on the SD card, please let me know!
