Attacking avalanche evolution

If the card already has a different playstyle plus before evolution then can only receive the press proven plus not the finesse plus , it says this before you evo. But if card has press proven before evo then you should get finesse too.  But there's a bug that doesn't let you receive finesse plus . If they'll give you another attacking avalanche or add the plus finesse or do nothing . Is anyone's guess . But when an evo didn't work properly before they gave those people another evo . Hope this helps
