MtG problem with card colours

[EldarVeteran]

I have put the Alara Reborn data file into Card Vault. Lots of the cards show up as colours, when in fact they are all Gold (as the whole set is Gold of course). Just one example is Ardent Plea, which shows up as white, when it is 1White, 1Blue, 1Clear. This means searches using the filter Gold does not find them. And in reverse, some show up in single colour searches (Ardent Plea coming up under white). Only 40 cards out of the set are correctly labelled.

I assume this is a problem of the MtG database?
