SSRS Report not displaying all the data for a user

I have a users that is having issues running the ledger transaction report. The report will run but will not display all the information on all rows.  Some rows display data and some do not.  I have cleared the users Usage Data as well as removed all the AUC files from C:\Users\USERID\AppData\Local

Does anyone know what other steps i can take to help resolve this issue?

Thanks

Eric
