Hi everyone, I have a fairly fresh install of zencart 151, I only have ckeditor and usps united states postal service plugins installed, when I go to "option name manager" and enter "color" as dropdown then go to "option value manager" and enter "white" all I get is this error

WARNING: An Error occurred, please refresh the page and try again.

I looked into the log and it gave me the following.......

[18-Oct-2012 14:03:31] PHP Fatal error: 1062: Duplicate entry '1-1' for key 'PRIMARY' :: insert into zen_products_options_values
(products_options_values_id, language_id, products_options_values_name, products_options_values_sort_order)
values ('1',
'1',
'White',
'0') in /home/lazer/public_html/includes/classes/db/mysql/query_factory.php on line 120

please help, I have no idea what is wrong.......

Thank you
