So you are viewing your SAS Web Report and find that all the data elements capitalizations have changed - instead of no caps or all caps, everything is prop cap (or at least PROPCASE). This is actually a default option in Information Map Studio.
To turn it off, select Tools Menu, choose Options. In the dialog box, click Data Items. Uncheck the "Capitalize the first letter of each word. (all other letters will be lowercased.)".
