Removing uninstalled vst instruments and effects Cubase Elements 12

I have uninstalled a few vst programs that I didn’t like or use. The names of the instruments or effects continue to show up in my library. How can I remove them from my Library? (I have the “Elements” version, if that makes difference.)

with the Steinberg Library Manager

The library manager does not show third party vst’s

What library are you talking about, if they’re not Steinberg products?

vst plugin manager in Studio
I appreciate your quick response

Have a look:

You are right, but how to I remove vst’s that I’ve uninstalled? The names still appear in the VST Manager.
