Supply order template problem

[Jebi]

Hi folks, so I'm trying to set up the supply order template system. When I'm editing the supply order template form with more than 81 products for the same supplier there is a problem when I save the template, a message appears:

 

Please verify the product information:XXXXXXXXXXXXXX

• Fieldquantity_expected is invalid.
  

 

Under 80 products in the template it works fine.

 

Does anybody know anything about this?

 

Thanks.
