Sales KIT not invoicing due to KIT not shipped

SOLVED

Hello, 

We are having an issue with our invoices not closing out because the actual kit is marked as 'backordered' as opposed to 'shipped'. However, all components of the kit have shipped.

For example, the KIT named ABC-KIT has 3 components:

ABC-001

ABC-002

ABC-003

The invoice shows:

ABC-KIT  Backordered.

ABC-001  Shipped.

ABC-002 Shipped.

ABC-003 Shipped.

Is there a simple flag to mark the kit as shipped? I feel like the solution should be easy but I am overlooking something.

Thanks!
