This no doubt occurs in several application templates. This particular one was noticed by Daryll Holland in the Reservations Page of the " Room and Equipment Reservations" template.
He solved it by editing the bottom webpart on the Reservations page with the XSL Editor.
(Naturally change the lcid number to the lcid number of your location - Finnish for instance is 1035; Italian (Italy) 1040)
Thanks to Darryl!
P.S. I tried doing this in Firefox and it's a complete disaster as you can't see the code properly in the small window they give you. So use IE where you click on the XSL Editor button to get a reasonably-sized window you can also expand.
