Reset quantize problem

I’ve quantized whole track on my project, but when I try to reset quantization on one marked part of track it resets quantization on whole track, not just marked one. I made my quantization through quantization panel.
Is it normal, and how to avoid this ?

thx in advance Zoran

Was the part a Shared Part (i.e. a Shared Copy, identical to the other Parts on that track?)

No, it’s just one part of track which I want to be unquantized. It happens C9 unquantize whole track not just part which is highlighted.

That is really strange… it is working as expected here.
