Is your NetBenefits account set to Simple mode in Quicken, where you see a dashboard with 4 big boxes when viewing the account rather than a list of transactions?
If so, you are experiencing a bug in the communication between Fidelity and Quicken. You can work around this by clicking on the gear at the top right of the account, selecting Edit Account Details, and setting the Tracking Method to Complete.
Please let us know if that explains your issue.
