Help with Variations in Version 3.9.4

I have the newest available version of the WP eCommerce Plug-in. I’m setting up variations of a product choices.

Example –
Okidata C711 printers variations:
Okidata C711n
Okidata C711dn
Okidata C711dtn

The plug-in is only showing one variation option. I’ve added all three, selected Generate Variations and the system returns only one product choice with the description of the longest option.

How can I resolve this issue?

Thank you.
Sherry
