Dmitry, yes you are right. I forgot to press Enter after editing a value.
So I have to press Enter for each value..in rf-tools 2 this was nicer (if I can remember)..I have only typed the value into the box and clicked the next row to enter a value instead of pressing enter and then go to the next row (2 movements instead of 1). Imagine I have 5 values, then I have to press 5x enter and 5x mouse instead of only 5x mouse.
