The SHIFT+CURSOR doesn't Work for Nudging notes MPC studio

In previous topics, it has been said to nudge a note(s) while T.C. is active, is to hold down SHIFT + drag with the CURSOR will Nudge the note(s). After trying this, it seems not to be working for me. Maybe i'm doing something wrong....

Please help me Plus i'm kind of new to MPC

Thank you!
