How to set ILS on 747 WT

Hi there How can I see the ILS indicator on the PFD of the 747 Working Title ? I’ve set the ILS frequency into the FMS (NAV/RAD) in place of VOR L. I can see the code and the DME corresponding in the lower left corner of the MFD, but I can’t see the ILS on the PFD and I can’t engage the APP mode.
