I'm seeing some strange results when users who are in 2 roles.

Both the roles restrict the dimension data on different attribute hierarchies within the same dimension. Both roles have the visual totals set to true.

If a user is in just one role then the dimension members returned and the visual totals works perfectly. (The Total at the bottom is reflective of the data returned.)

If a user is in 2 roles then the dimension members returned is fine but total displayed is the total aggregate for that hierarchy and not the visual Total I'm expecting

Both sets of users (1 role and 2 roles) see exactly the same data returned it's just the totals are different.
Any idea whats happening here?
