BEAT FX on screen display disappeared using FLX4

Sirs,

I've updated to Rekordbox 6.8.1 and the on screen BEAT FX display has disappeared.

Previously when I pressed FX SELECT button, the effects would appear on the laptop screen and I could press the button again as the selected effect scrolled down the screen.

Now when I press the BEAT FX button, nothing appears.

Is there a new parameter in setting I need to set.

Worked fine before, why change it!

Steve
