Unable to add products to pack

[alejandrosl]

Hello,

 

I'm trying to create a pack that should include two different products, these products already exist. So I create a new product, I select "pack" as product type, but when I type the first letters of a product name as indicated, they delete themselves and then I can't get the product list to select the products for my pack. Anyone knows if this is a bug and how can I solve it? I have found this behaviour with several browsers and operating systems. I'm using PrestaShop 1.5.4.1, with backoffice and frontoffice in Spanish, and Simple Responsive Theme.
