Autonumber missing values?

Autonumber missing values?

Hello,

I have added an auto number field that is to generate and identify a new purchase and sale upon form submission.

The number does not show in any report ... or anywhere.  Yes I have tested by submitting forms... 

Is this a bug? Is there a fix?

It seems a simple thing but I seem to remember it was an issue during my trial of creator from years ago and 100% critical in my using the platform.

Thanks!!
