Numbering Missing -Quotes copied to Sale Orders- Copies to Invoices

Say you save a quote numbered 1.
This one

And then you copy it to a new sales order, the numbering is missing, and there isnt something poiting back to the quote:

So, you enter lets say a number, 123, and we update it.

Now lets copy it to a new sales invoice.
You will see that the Sales quote number is missing.

Am I missing something?
