Error creating 1 specific product (An element with the same alias already exist)

Error Saving

When I'm trying to create the product 'Zout', I get the error "An element with the same alias already exist"
Other products are created without any problem.
Where / how can I find that product Zout? Any other tip to resolve this issue?
Thanks in advance
Guy

PS zout2, zout3 are also rejected.
