OK then. If you didn't reboot before you installed the other then you had the app in both system AND data, Lmfao. You could have left it alone and just install the other one to overwrite it, Lol. BTW, ANY TETHER will heat up the phone a good bit..
Try reinstalling the ROM with Philz Touch and follow my directions about settings in tether. That should make things 100% as expected. I'm advising reinstallation due to TWRP being weird, this could also be an underlying cause of things not being Str8. Just don't forget to remove the 91touchscreen script from init.d.
