lost customization product attributes previous adding to cart

[javitineo]

Hello, access the web https://www.globyshop.com/globos-numeros-grandes-inflados-con-helio/9201019-globo-numero-0-oro-de-foil-talla-xxl-90cm.html  trying to add a product to the basket, we will give them that they must fill in personalized information that is requested. Once made and stored, we accept the product to the cart without problem. No problem, in firefox and chrome, but in IE 11, when adding to the cart it tells me that I must measure the customizable data again, and indeed, I see that they have been lost, so I will not be able to measure that item in the basket. I am using the amazing_gift template. Any ideas?

have you checked with the theme developer? Likely a template issue.
