How To: delete Local User Scenes including icons in DS?

in New Users
How do I delete, from the Local User section of Daz Studio, the Local User Scenes?
I can find the files and delete them, but the icons remain in the interface panel with notices that the files are gone.
It may be obvious, I appologize in advance for my lameness.
TIA
Jay

Find them in the Content Library under Categories, right-click and there should be a Remove Reference command.
