Double clicks not working

So I am on the latest 8.5.2. I upgraded to OS Sierra. Since doing that when I double click something like a midi region. Sometimes it opens the editor as it should. Sometimes it doesn’t. Very random. Very annoying. Only since Sierra.

I also confirmed that the double click on the Macbook Pro Trackpad works perfectly fine. This issue is only on my Magic Mouse 2, since Sierra.

Hello, I have the same issue. Has this problem been solved?
