Windows 10: How to disable left shift key toggling fn lock

My left shift key keeps toggling my fn lock on and off. Does anyone know how to disable the shift key from doing this?My left arrow key also keeps highlighting text to the left of the cursor whenever I use it as opposed to just moving the cursor to the left. Does anyone know how to stop it from highlighting?My left ctrl shortcuts like ctrl+c and Ctrl+v also are not working, but my right Ctrl shortcuts do work. Does anyone know how to fix this?
