Promo Pack Importing

The promo packs you get at events tend to have troubles importing.

I'm not sure if the problem is with Deckbox, Moxfield, or the MTV CSV Helper tool I use. However, When I export from Moxfield for example:

Moxfield Export: Assemble the Players, pmkm, 3p
Deckbox Export: Assemble the Players, Murders at Karlov Manor Promo Pack, PP_MKM 3
CSV Helper Moxfield to Deckbox Export: Assemble the players, Murders at Karlov Manor Promos, 3p

This is just one example. But nearly all promo pack cards if not all have this problem currently.
