Problem:
When running a Horizontal Geometry Report (or any geometry report), I am getting question marks (??) instead of a plus sign (+) for the station delimeter?
Solution:
In the Bentley Civil Report Browser, go to Tools>Format and make sure the Station Delimeter is set to +. In some cases, this field can be set to an unrecognized character (example in the image below.) Changing the delimeter to + will resolve the issue.
