Error in combination Generator

[singhdeepakrana]

Hi

i am implementing a prestashop at the following url

http://test5.stokplas.com/index.php?id_product=8&controller=product

 

i used the combination generator to get few combination and add another attribute called voltage.

 

the error is that when i use this voltage attribute in the product combination and select it from the product page i get a negative sign in the page url and for all other attributes i get their normal description for example

http://test5.stokplas.com/index.php?id_product=8&controller=product#/color-blue/disk_space-80gb_20000_songs/-

 

the /- at the very end is for voltage selection.

Am i creating the attributes in a wrong way.

Please help.

Regards
