Using 1.39,

Trying to assign attribute values, each time I try and create an attribute I get the following error message:

1062 Duplicate entry '1-1' for key 1
in:
[insert into products_options_values (products_options_values_id, language_id, products_options_values_name, products_options_values_sort_order) values ('1', '1', 'Red', '1')]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.


Any ideas?
