What are these MIDI param sliders, how to get rid of them?

I am working on a VST3 plugin using IPlugResponsiveUI as base.

In Reaper this plugin and IPlugResponsiveUI have all these sliders in UI mode (the list goes on…), where do these come from? Any way to get rid of them? Its not a deal breaker but would rather not have them.

Thanks
