lost civilization map not updating

when i looked in the market place it said there is a new update for the lost civilization map. but after it was done downloading the update it still says update instead of owned. i checked how much ipad storage i had. i had a lot of space available but even though i tryed to update the map it still wont update. it worked on the ready sled go map updated to 1.0.4 to 1.0.5 but the lost civilization map is still at 1.0.4.
