Hi Elias1957,
the included programs and presets of a library should vanish after removing a library via the Steinberg Library Manager. But newly created (user) programs/presets will remain in the mediabay right now, even if the corresponding library will be deleted. This makes no sense as this will clutter the mediabay with unusable stuff. Its now in our Defect-Tracking-System and listed as Bug-ID “HALLY-7732”.
I hope we can provide a fix for it soon.
Thanks for your report and please accept my apologies for any inconvenience caused.
