Client Group Settings Override / Invoice Date Settings Not Working

[dcapone]

I am unsure if this is a bug and affecting everybody or if I am doing something wrong.  Essentially I have created a product and set the product "generate invoices" setting to zero expecting the invoice for the product to generated on the due date.  The customer we have assigned this product to is having the invoiced generated 7 days in advance of the due date instead of on the due date as expected.  I am unsure if this is because we may have changed the setting for generate invoices after we added the product to the customer?  I was hoping that adjusting that setting would automatically change all future automation with the product, but that does not appear to be happening.  To circumvent the issue, I attempted to create a client group for all of my clients and set the automation override setting to 0 days.  That also does not appear to have corrected the issue.  Is the automation essentially set in stone once the customer account is initially setup as opposed to varying with changes in the various settings?

Any insight would be appreciated.
