Disabled controls have to show their correct state. Neither the state nor
any other property should not be treated as "doesn't matter". If on/off
really does not have consequences in the specific situation it should be set
to the default.

A control must not be hidden unless it never applies (to the current user
for instance). 

In my opinion the actual dialog behaves correct. One doesn't have  the
option to move a sheet, and to copy is the default. Both items are grouped
(usually for radiobuttons) so both are disabled. 
If one (or more) items of a group are disabled but user can still choose
from other items, that would sends some kind of schizophrenic signal to
users.
