PO Status changed to "Submitted" - used to be "To Receive and Bill"

Hi all -

I’m not sure this is a bad thing, but as of today my Purchase Orders show “Submitted” after being submitted. They used to always show “To Receive and Bill” after being submitted.

The only change i made today was to change the naming series on POs to include the Project number.

Any thoughts on what may be causing this?

Thanks
