Numerbay - Duplicated Numerai Wallet

When I try to add api keys to my Numerbay account and try to save them I receive the error message :

Duplicated Numerai Wallet

The keys are not saved so I cannot connect my Numerbay account to my Numerai account.

Please excuse me if this is the wrong forum to raise this issue but I am struggling trying to find a way of contacting Numerbay support.

Does anybody know of any way of getting support for Numerbay to resolve issues like this ?
