Media seem to be downloaded but links are not replaced

[nnbveh]

I've processed a deck, and i can see that the media is added to it, because when i've synced it on android in downloaded the media, but if i try to use the deck offline the media is not displayed...at the same time, when i've tried to export this updated deck its size is basically the same as of the one without internalized media, so i'm confused...
deck.zip
