Problem with a Point probe in thermal problem

Hi everybody. I hope someone can help me with a little problem I have with a point probe. I have edited my previous message to include more data and the mph file.

The problem is as follows:

I am analyzing the temperature of an underground power cable, so I defined some point probes to measure the temperature on the different layers of the cable. When I first solve the problem, Comsol automatically creates a plot with the data obtained by the probes. If I change the depth of the cable (which is a parameter), it is supposed that the probes will move with the cable. However, the data shown by the probe plot are taken in the previous location of the cable.
I think something strange is happening because during the computation, I can see the data from the probes in the progress window and they are correct. So I decided to update the probe table (clicking on the update icon), but nothing happens. But if I evaluate again the probes on the "derived values" node, then I have a table for each probe with the correct data. It seems that the probe table generated automatically by Comsol doesn't take into account the changes in the parameters.

Am I doing something wrong?

Thanks in advance.
