VDD of padring not connected to VDD of core ring via power pad

Hello,
I am having trouble connecting the VSS and VDD nets of the padring with the core VDD/VSS. I have created a core power ring, and after running sroute the power pads are connected to the VSS and VDD of the padring, and they are also connected the the core ring (on the CLASS CORE ports VDD/VSS of the power pads).

But if I run verifyConnectivity I get violations: "Special Wires: Pieces of the net are not connected together." The reason for this warning seems to be that SoC Encounter does not see that the different VSS/VDD ports of the power pad are connected internally.

A quick check by manually connecting the pad ring VDD with the core ring VDD (using a wire, not via the power pad) makes the violation disappear.

What could be the reason that SoC Encounter does not see the connection between the different VDD ports of the power pad?

The VDD and VSS nets are connected logically using globalNetConnect.

Here is a snippet of the LEF for the power pad:

        END
    END VDD
