[solved -> wrong german translation] Item harvester Bug

[Kolars]

I have used the item harvester, but nope it says I would get 50% additional iron instead of items? Is just the text wrong, or do I now get more iron? Both would be a bug.
Screenshots are in German, sorry:

1. item used: Item harvester - get 50% additional items from season 1
   

   

2. item description after using it: Item harvester - get 50% additional iron from season 1
   

   

Game Version: 27.0.0 Build 714
iOS Version: 13.3.1

I do not need iron, but adventure kits

Thank you for clarifying!
