Archiving Maps online deletes saved maps from device

Caution. I don't think it used to be this way. So I think this is either a bug or a change. I finally got a sync to work on one of my devices that had multiple maps on it. The trouble is that it deleted about 10 maps from the device. I had the maps archived online trying to load them one by one on a new device (required to keep sync from crashing if you try to sync multiple at once).  I believe in the past, that you had to delete the maps from the device itself to remove them (sync would not) - archiving them would just keep them from syncing to a new device (or updating on old).
