Hi there!
I might have forgot to add those options to the default preset, you can easily make a fix until it gets fixed in the next update:
1. Open JuiceFX.
2. Without changing any value, go to "Save Preset" and save the preset as "default.jpf"
3. Move the preset to the app's root folder and overwrite the current "default.jpf"
And that's it, when creating a new project it should load the new "default.jpf" preset and it should update those values.
