Do you know where do "Desctriptions" are saved in ProfiluxControl?

I am talking about Description field in each part of PrifiluxControl. For example in Timer 1: "This is a timer for heater in tank number 1". After I wrote this Description I pressed "Save" and next "Load".
But after next connection with PC ProfiluxControl I did not find any Description in this field in Timer 1.

OR:
How can I save my Descriptions in ProfiluxControl?
