TRL - Return Loss Discontinuities

After performing a PCB TRL (depending on the board used), when I do a cable measurement I get nasty discontinuities in my RL at the frequency break points (start/stop freqs for each line standard). Any idea what this could be? I've seen this issue a lot. Dr. Joel, is there anywhere in your book that discusses this? I've attached an example pic of what I'm talking about?
