It would appear that there are two streets with the same name causing reports to list a street twice.
The streets file cannot have duplicates. It is more likely that one street is mis-spelled with one or more leading or trailing spaces (see also IMW0005).
Navigate to ‘reportslistingsstreets in database’, you will get a listing of streets (be sure to click on the FOR CHANGES radio button). You will need to find the two streets that look identical, and change the bad street to match exactly the good street (WITHOUT trailing or leading spaces). Answer OK to overwrite the file and then nav to ‘utilitiesdatabasechange streets’. Answer affirmatively to all prompts and you should get a message to the effect that 1 street has been removed and one added.
