Invoicing oddities #4182

I was trying to update the invoice settings for our March dues renewal. When there is no text in the custom message, the default invoice message does not appear at all. When I add text to the custom message, I get both my text (unformatted) AND the default message as a sidebar. I thought maybe it was a quirk in the display, so I emailed one to myself and that's what the email looks like as well. Screen shot attached. "Double or nothing". 

I've attached screen shots of the admin setup as well. 

While I look into this if you put your message in the after box. it will show.
You can copy the default message and put in the after box and you can manipulate.
