The layout is slightly different now it's all css based - do you mean that or do you mean there are items showing in the wrong place? Did you force a refresh on the invoice screen?
Forced refresh on adminorders.asp orders view, order details view and invoice view in Chrome, Edge, FireFox. Noticed the change in layout, but all css seems to have vanished and things appear haphazard. Tried uploading a screen shot, but didn't find a quick way to do it.
Would you like to send em an email with the login details and I'll take a look for you. It won't be cached for me so I can tell you if there is a problem or not.
You may need to force another refresh in the admin orders page to see the changes but can you check the Additional Information field and shipping method are now showing correctly?
