SuperSU Boot Loop, DL8006 Tablet

I wanted to do a build using SuperSU instead of Magisk (which runs great, no issue). However, after I flash from the TWRP I compiled for it, it will endlessly sit on the boot screen. TWRP said things went where they belonged, no errors listed. The bootloader isn’t really locked on these things, you can unlock it if you want but it isn’t entirely necessary. I tested without unlocking. What would cause a SuperSU build to fail where a Magisk one runs fine?
