Thank you so much for checking all this cretakano!
yes i did many factory resets - +drive was never installed - I am first owner.
its definitely a bug in the os and I guess it will never be fixed anymore - which is a pity - because if you want to use the user waveform you have to downgrade to OS1.31D and if you want the new and nice functionalities they added in OS 1.32 you have to updgrade back to OS1.32B
tried really everything - but do not get it going… 
thanks again!
