Mercenary packs

I recently bought the 2 new bundles in mercenaries for packs / legendary packs. The legendary packs auto opened and didnt even show who i acquired so i dont know if those even worked. and the 50 packs that they came with half of them contained only coins for example i open one pack and it was only coins and no card or portrait at all. Under the description of the mercenary packs it says they should give at least 1 rare or better card until all are acquired, so either this is a form of mislabeling or it is bugged and not giving cards properly.

If the pack contain a rare Card, and you have all, You obtain a portrait rare, if You have all You gain money
