Composite products

Hi, I’m setting up some compositions for some products and I get to the 14th component and the product will not save. It comes up with the following error:

The quantities you entered for ‘Item 14’ were not valid and have been reset. Please enter positive integer values, with Quantity Min greater than or equal to Quantity Max.

The Min. and Max. quantities are both set to 1. I don’t have this error on components 1 – 13.

If anyone has had this issue before I’d be grateful for any tips to resolve it.
