Everytime crafting a Decorated Pot, the one in the Creative Inventory changes to the last one you created

Cannot descript clearly until I upload a video about that.

How to Produce

1. Check out the Decorated Pot in the Creative Inventory first
2. Craft one with custom Pottery Shards
3. Go back and check the one in the Creative Inventory

(×) The one in Creative Inventory also changes rather 'an keeping default.
