I am using prestashop v1.5.1 (spanish version) Bug: If i go to Products section, and make ANY change (in any of the categories: price, seo, etc...) when I click on "save" or "save and stay" (I dont know if that is the english translation because I am looging at the options in spanish), the quantity of the product is reset to 0. The only way I have found to be able to save product quantity is to go to the quantity section, write the quantity and then click outside the textfield. This action saves immediately the quantity (it looks like a jquery save). If I then click on save button, the quantity is reset again with 0 value!
