Freeze tail duration

Is it normal that "Freeze tail duration" works only for freezing Track FX? I wanted to freeze synth and let effects working to set them, and I disabled "Track FX" in freeze options. It lead freezing to hard cut audio after last note ending. But synth sound has long release and it is unacceptable, and I believe tail must be added anyway if there is setting for it.

You can set a render tail length here:

I guess I need to figure out how this is happening.  I'm getting the same result regardless of the Clip Tail Duration setting.
 

Got it ...
