Problems in setting FTP and Power Zones

[bugifa]

Using the new version of the app I noticed that there is the possibility to add FTP and power zones in the parameters menu.
However, when I set the FTP and try to generate the power zones nothing is actually generated. Additionally, closing the parameters menu and re-opening it the FTP value set is lost and "0" is displayed.
Am I making some mistake or this is a bug? Any other with the same issue?
Thank you for helping
