I hope I am missing something obvious again. This time a question on default settings for printing invoices from the Invoice module.

I don't think I have clear understanding of the default invoice settings:

1. What "rules the roost" so to speak on the default invoice settings - Receivables or Invoices since I can set them in either place.
2. If the customer record is blank for a default invoice setting does it look back and read the default invoice setting in Receivables or Invoices? And if in fact it is supposed to do this then why doesn't the correct specification appear when I go to print the invoice?
3. If the customer record does have a default invoice specification picked out I assume this over rides the setting in either company profile? Again as in the previous point this is not happening

Here is the confusion. Regardless of what settings I have in either the customer record or either profile when I go to print an invoice I still brings up the incorrect setting and ignores what I have already set up (see pic attached).

Then to take this a step further after I have reset to the correct specification it holds these settings for the next invoice for a customer who might be setup completely different.

So if a user changes these settings then the next user that comes along has to change back and so on.

So hope this makes sense and I look like a fool here since I am confused.

Thanks in advance.
