User groups cannot see any data that I am providing them in a report

I have 5 uderlying source files with emails on each line that I am using to give the user access to just their data. In the report I am giving them access to I put all 5 underlying sheets in the what and in the Who I used two different email columns in the data to give access to employees and their managers. I used an OR function to allow them to see just their data. Everything is working for the employees but the managers go in and they see nothing in the report when they open it. I have given them edit no share access to the underlying source reports as well as the report that they ultimately are openning. Still I they cannot see anything. I have also verified that their log in email/username is the same email that is in the source reports. I am at a loss.
