SmartSheet report sharing


Hi there, I have created a report that pulls from 2 source sheets. I have added my client as a Collaborator (Viewer) to both source sheets. When she goes to the report, she can only see data being pulled from one of the 2 sheets. What am I doing wrong? I cannot figure out why she is unable to view the rest of the data. I tested with a different individual, and he can view the full report.
