Keyboard Shortcut for Memory Loop 1 Active On/Off Gives Error

Hi, 

First, the specs:

Rekordbox 5.2.3, DVS

Macbook Air (13-inch Early 2015)

OSX 10.13.4 

In performance mode when I try to use the keyboard ("c" or ".") to activate a memory loop on or off, I get the red error on the bottom of the window: "Invalid operation: Set Memory Loop". This strikes me as odd since the function assigned to the key is actually called "Memory Loop 1 Active On/Off". I couldn't find a function that matches the error.

Fixing this would be a big help. When I decide I don't want a currently active memory loop to be active, and setting that loop to off means that a click slightly off center of the memory loop symbol will cause the track to abruptly jump to that point and stay there, I have to either live with the memory loop or mix out sooner than I want to. Thanks for any help!
