I have the same issue and this is a pain in the but because it takes so much more time
It definitely is a pain as I now have to start my edit in Premiere CC 2018 and then finish up in CC 2019. Being efficient with keyboard shortcuts is crucial and I can't afford wasting time using my mouse every time I toggle between my panels to select the next item on the list.
You're a lifesaver! That worked for me!
These would be the steps to follow:
1) trash preference
2) change the keyboard shortcut to remove "CMD+"
