Product Code displays option numbers

-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.4.5
-- PHP version -- : 5.3.28
-- Browser(s) name and version -- : Chrome

Hello, I have turned on the button to let the product code display on my products which works fine. But when on the product page it also add the numbers of the options to the end of the product code. is there a way to remove these extra numbers.

Thanks Phil

I have solved this myself now. It was because the variants each had there own code too.
