[#14606] - Having trouble loading a security file in a domain

Hello I am trying to implement a new security file on my jaspersoft instance and am getting the following errors when trying to save my domain. I do not think this is an XML error but possibly something more specific to jaspersoft server when trying to load the file. otherwise i am not sure why this isn't working. Any help on this would be greatly appreciated!

There is a problem with the security file
The following field(s) can not be found:

The filter condition 'testProfileAttribute(dw_analytics_dim_faculty.faculty_username, 'username')' references one or more fields that cannot be found: ID [dw_analytics_dim_faculty.faculty_username].
The filter condition 'testProfileAttribute(dw_analytics_dim_graders_rls.grader_username, 'username')' references one or more fields that cannot be found: ID [dw_analytics_dim_graders_rls.grader_username].
The filter condition 'testProfileAttribute(dw_analytics_dim_coach.coach_username, 'username')' references one or more fields that cannot be found: ID [dw_analytics_dim_coach.coach_username].
The filter condition 'testProfileAttribute(dw_analytics_users_workspaces_rls.username, 'username')' references one or more fields that cannot be found: ID [dw_analytics_users_workspaces_rls.username].

here is my formatted XML:
