I customise my keyboard to make my workflow easy. I believe everyone else does the same.
I use the key Q to split a clip in my timeline.
Now when I close PE and open it cannot restore that Q key's function. I have to navigate Edit - Keyboard... and close that window to restore the function.
Not only the split function restore, some functions do not even work. I have found Delete and Close Gap function in more than one place, when I assign a key, it works in certain places and then it do not.
Error or problem
