Thanks to multiple duplicated items issues i went to check on my tattoos and found another bug that first i thought might be another duplicate problem, but instead it's just a text error.
The Auki Sign Schemes are from Flying Papers and those are unlocking the proper Auki Sign tattoos, but there's a different set of Auki Sign Schemes sold by the Mechants.
Those from the Mechant use the wrong names and instead of Auki Sign tattoos those are unlocking the Dupuytren tattoos and shold use the Dupuytren Scheme (...) name.

Rename the Auki Sign Schemes sold by the Merchant to Dupuytren Schemes
