Visible time cards in project

While changing permissions in the Roles Module for one of our employees, I’ve set the Timecard’s module to “Full Access - Own Data”. I’ve done this to limit our employees from viewing other Employees timecards. However, I’ve noticed if you navigate to the Time Tab of any Project file, it still displays other people’s timecards. This could potentially allow users to calculate the wadge of others based on the number of hours worked, and the committed labor cost.
