Picking up Kraken's Eye near Hall of the Unseen messes up enchanting

[daerragh]

EDIT: OK, after reading about kraken's eye on the forums I now think it's not a bug but a feature...

 

There's an undiscovered island below Tikiwara, it looks like a volcanic island. On this island south-east from the Hall of the Unseen the party can pickup Kraken's Eye from a location that looks like a camp. However picking it up makes enchanting buggy: now for every upgradeable item there are 2 Superb enchantments to choose from. 

I'm using the latest GOG release with all DLCs.
