Overlapping MSI-X table and PBA

I have a (prototype) PCIe device that shows the following in pciconf -lc:

    cap 11[70] = MSI-X supports 5 messages
                 Table in map 0x1c[0x0], PBA in map 0x1c[0x0]

This is completely bogus, right?  I don't see how the MSI-X table
can't occupy the same offset in the same BAR as the PBA (certainly the
datasheet for this device says that they should have different
offsets).
