[Gameplay] "Lots of Honey" item stays in inventory after festival

[WaddlyDoo]

The "Lots of Honey" item you receive from Luke stays in your inventory even after completing the Royal Jelly quest. Is this a bug? It presents no problems with gameplay, it just.... sits there. Could someone verify whether or not this is a bug?

I think I've had a similar bug, where a quest hand-in item stays in your inventory. Instead I have it with Amalet.

Just completed Mount Bloom and still have Amalet in my inventory

I also still have both, Amalet and Lots of Honey.

Checked again and found Lots of Honey in my inventory as well.
This clutters the key items section up a little. Does anyone knows why the Yeti dolls are in there too?
Are they really a key item? I have 25 of them so I somehow doubt it
