Cannot find the Fade in and out notches

Hello all,
I'm using Da Vinci Resolve 16 on both Mac OS X last version and Windows 10.
It's been 2 days that on Mac OS X I cannot fade in and out music nor videos because the little notches that I need to move to do fade do not appear at all (nor clicking, nor passing the mouse over) on both video clips and music (even titles).

What I'm doing wrong?

Thanks

Never mind, I figured it out. I have just to expand more the video or soundtrack panel of the left. If it's too narrow it doesn't show the notches.

I had the same issue and couldn't find out the problem. Thank you!
