Fedex Intl Economy net wt of each commodity rounds down to whole number

For Fedex Intl Economy, the net weight of each commodity rounds down to a whole number.

Steps to reproduce:
- Create a new shipment for Fedex Intl Economy
- Add five commodities
- Screen shows: Total weight 4.35
- Hit "Ship" button
- The printed Commercial Invoice shows Net Weight 0.00 for three of the items and 1.00 for two of the items. And it shows Total Net Weight 2.00 LB

The weights are not correct.

Thanks,
