"Nudge: Link to Grid On/Off" works with time grid, but not with beat grid

Hi!
I’m having trouble with the “Nudge: Link to Grid On/Off” command in Nuendo. When I set the grid to time (like 1000ms) and Link to Grid is On, nudging moves events by 1000ms. But if I turn it Off, it moves by a bigger interval.

When I set the grid to beats, it works fine with Link to Grid On (moves by 1 beat), but with Link to Grid Off, the events don’t move at all. Is this a bug or am I missing something?

Thanks.

Found a Solution: if you open Nuendo for the first time on a new computer, using the command “Nudge: Link to Grid Off” will leave you with unselected nudge value, so nudging an Event won’t move it at all.
It appears that there’s no default value for nudging, so you have to select some value for “Nudge” and then toggling “Nudge: Link to Grid On/Off” will work properly.
