Clips Loop playback cmd+L doesn't work

Hi there , I can't get to play a clip in loop with the cmd+L comand ; I looked at the shortcuts and it's correctly set up but it doesn't work .
Even when I try to play in loop using the comand from the menu " view " window It doesn't work either .

I'm using fcpx 10.3 on a mac book pro with Sierra installed .

In my previous verision of fcpx 10.1 that comand was working .

Any idea how fix it ?

I use it all day long, it should work.

Try this, as I've found it sometimes helps. Go to System Preference, to Keyboard, to Shortcuts, and click the "Restore Defaults" button.

You mean in Final Cut , or my mac system prefernce ?

The problem is that here in Europe we don't have a dedicated / key , to get that I gotta hit shifi+7 , but in this case doesn't work to play the selection .

Exactly what keyboard are you using? Some will not work correctly with FCP. What keys are in the bottom row on the right?
