It seems like this is a bug for these components.
The Sample Rate is taking a numeric value between 0.5 and 0.65 for it to function properly. 0.5 is the minimum = 44100Hz. You cannot use the frequency mode on the sliders for this. Same for the PostFilter while this one takes values between 0 and 1.0, using a Frequency Slider results in a Crash of Hise.
