Current User Filter showing blank report

I am trying to use the current user filter for a report I setup. The filter is based on the Project Manager Contact List Column and the report should show records when the Project Manager column is = Current User. It works for me but no one else. The people have editor rights to the underlying sheet and to the report itself.

The filter is Project Manager --- Has any of --- 1 value selected (Current User).

I've also confirmed the users are logged into smartsheet with their correct email/user name.

Any thoughts?
