Real Nets not Annotated

I am having a lot of difficulty with a flip chip Area IO design. In the design, the IO cell with pin PAD is connected to a BUMP using fcRoute (wide top level metal, low resistance). When I run report_annotated_parasitics command I can see all of my real nets are annotated except for the 131 bi-directional top level nets connected PAD to BUMP. Is there a way to debug why these nets are not annotated?
