skr 1.4 turbo tmc2209// Marlin Z endstop inverted at all times

[mklsmu]

Hey, so I was setting up my new SKR1.4T with tmc2209 drivers for my Ender 3 pro. Everything was running smoothly until the first homing. I'm using sensorless homing on the X and Y axis and that's working perfectly. When I tried to home the Z-axis it just went a Lil bit up. I typed M119 in Pronterface to see if the endstop is triggered, and it was. When I tried to press it manually with my finger it said open. So obviously I tried to invert my Z Min endstop in marlin, did this for like 4 times and all the times it was the same, always inverted. I have cut the UART pin on the z driver as shown in the instruction manual. Thanks, Sam
