I'm ashamed to say this, but ...
I've actually figured it out. It seems that I haven't looted the items from the cupboard in the first place *facepalm*.
@Thom Karnel, you have to to access the cupboard behind the Meistr by using the 'cogwheel' feature then a dialogue pop-up will be displayed where you can retrieve the items.
SORRY. BIG SORRY.
