How to change parameters?

When connected to the drone I go to the parameters section and click to refresh. Next I change RATE_RLL_P from 0.144 to 0.12. Next I press write and Droidplanner says that 1 parameter was written. When I refresh the parameters again the old value of 0.144 reappears. Am I doing something wrong or did I stumble upon a bug?



Really no answer anyone?
