Don't have it set to post.
I did notice that I don't have this problem if I'm not using an FX Chain.
Could you try the above with an FX chain loaded?
I have this problem with three different ProChannel presets that all use Concrete Limiter and an FX Chain loads in the preset.
(All three FX Chains are different and no two FX Chains have the same vst loaded, one has a multi-band compressor, another has a tape emulator and the third has a spectrum analyzer loaded in it)
