Hi Emma,
You say "The number of copies to keep should be deleting older ones but only in the location that you are backing up to.".
I'm not OK with you : why would one expect number of copies to keep to apply ONLY on the current location?
In fact, i think that the best approach would be to have an option to tick (or not), saying "Delete older copies everywhere (not only the current place)", that would remove all old backup copies...
