Not All Answers In Manual, Unable to save multimode patch to new location

[Darwin43]

Hi,
I am unable to save edited multimode patch/configurations to a new location. TI does nothing when I press store
I am able to edit a multimode patch/configuration and then save it to the same multimode location.
(for example, i call up in multimode xyz at location ( lets say 0 ), I make a few edits , then I try to save the edited multimode to a different location (lets say (127) so that i can keep the original multimode configuration.
When I press store nothing happens unless I try to save it to its original location of (0) , and therefore the original multimode config will be overwritten, which I don't want
Any ideas??
Thanks
