Nanjing Fardriver stuck setting

I have a Nanjing ND72360 Controller and some part of the setting is not configurable. I would try to input the desired value but nothing changes.

It's in this Ratio in speed setting, the ones where the value is 0% can't be changed.
then also in this setting "LmtSpdMaxCoeff" isn't changeable. Have anyone ever encountered this problem before?

Yes had the same thing with my 721800 , could only change the first two values in the ratios of speed with the new app.

I change values with the old ap 1.5.5. and save them with the new ap 2.4.9 or now with 2.5.0. , because the old app does not save the values. Probably this has also something to do with the binding process.
Not nice but it works for me.

My controller works only with the old BLE and does not connect with a new BLE.
Also I can´t save with the PC-Software , I can only change values, but not save it.
