Users List is Empty in Reports Module

[rmoss]

We are using the open source version of 5.5.x (I thought it was 5.5.4, but our help file says 5.5.2, so it is one of those). When we click the option for REPORTS and choose the pre-defined report called User Tracker Report, we are asked for a date range and we see a drop down list for USERS. The drop down list is empty, though. I do not see an option in the setup screens for users to say whether to include those users in these types of lists. I also do not see anything in the drop down editor about a users list. Lastly, I see nothing in the regular Studio area that will allow me to turn on the list. I am an admin user so I doubt the problem is related to lacking rights on a ROLES screen to see the user list.

I suspect user error and lack of experience here, but since I found no other posts by people with empty user lists, I thought I would see if anyone has any ideas. Our Sugar was set up by someone else and he is sometimes available to help fix things, but we are trying to learn how to be more self sufficient.

Thanks to anyone with a spare moment to offer a suggestion.

Can you reproduce this issue in a fresh install with demo data?
