Issues with importing from CSV

TL;DR There are some problems with Planeshift "Alternative Art Foil" cards and some of the "Full Art" lands from BFZ during import from a CSV file.

So, I exported my MTG collection to a CSV file and imported it to my brother's account. The process itself went smoothly (about 4900 entries), but I've noticed that the total collection value is slightly different. Upon further investigation I found cards that were imported (or exported) incorrectly.

I own Skyship Weatherlight and Tahngarth, Talruum Hero from Planeshift in normal versions, but they were imported as "Alternate Art Foil" (so for example this - https://deckbox.org/mtg/Skyship%20Weath … mp;lang=us).

Other issue that I found was with some of the (but not all) Battle of Zendikar "Full Art" lands. I own this Forest - https://deckbox.org/mtg/Forest?printing … mp;lang=us, this Plains - https://deckbox.org/mtg/Plains?printing … mp;lang=us, and this Mountain - https://deckbox.org/mtg/Mountain?printi … mp;lang=us in "Full Art" versions, but they were imported as normal versions. But some of the "Full Art" BFZ lands that I own and exported were imported correctly.
