Issue with Woocommerce Composite Products plugin

Hi,
We are using your plugin to add gift card messages to our gift hampers, created with Woocommerce Composite Products plugin (official).
All works well, except when the order comes through, the gift message shows not just for the hamper – but for every product within the hampers too.
It should show just for the main hamper. Any help resolving this would be appreciated.
