CSV Import ends with error "Property SpecificPrice->reduction is not valid"

[Jack7]

Hi everyone!

 

Does anybody have any idea where is the problem? I am trying to update products throught CSV Import and it end with the error below.

 

Lately we moved our eshop to new hosting. Before then it never happened.

 

The eshop is on 1.6.0.14 version of Prestashop.

 

Thank you for your ideas!
