Fwego; This should be fixed in the next major update (no ETA yet, as there are still things to be added before full testing can start), in saves before the quest is completed (when you can still ask her about training).
Liska22; When I try this the items are not removed, just added to wares and moved to the next open slot (I think still a bug, unless Shift moving is meant as a shortcut for adding things to wares).
