Error Products For Shipment Were Not Selected

We are using CS-Cart version 2.24 and just started getting this error when trying to enter a shipment and tracking number.

[color=#9C3535][font=Tahoma, Arial, Verdana,]Error [/font][/color][color=#9C3535][font=Tahoma, Arial, Verdana,]Products for shipment were not selected[/font][/color]

Even though we do select the products, we are getting this error.

[font=arial, helvetica, sans-serif]So now we can’t enter and email a UPS tracking number to our customers.[/font]

Any ideas why this might be happening.

Thanks so much!
