roller shutter 2 percentage problems

[Nomader]

I bought 5 of those (v2.5) for my shutters and tents.
They work ok (but not quiet)
The percentage is not working as it should, and i am not sure what is to blame.
Once i calibrate everything works ok until randomly (1 day or 2) a shutter will forget the calibration and will show garbage for example 30% when it should actually show 100%.
Then i calibrate again... and so on
Mind you that the buttons are toggle buttons and are used by members of my family often..
I think the implementation of the percentage in the fgr-222 has some issues..

i might as well answer to my self since the forum is a bit slow on answers.. And i am sure that this will be handy for many
I managed to solve the problem by replacing all my toggle switches to momentary.
According to fibaro, the fgr-222 works with both type of switches.. but according to my experience it does not work well with toggle.
