bbPress (Twenty Ten) 1.2 by WordPress and bbPress teams remoival from Appearence

Hi,

bbPress (Twenty Ten) 1.2 by WordPress and bbPress teams

This theme is not enabled, but persists in my users >Dashboard>Appearence>Themes>.

It is apparently like a child theme of Twenty Ten which is not Network enabled and is properly not listed under Dashboard>Appearence>Themes>.

I tried to delete the bbPress theme, but it never it went away. When I delete the Twenty Ten theme then there is an error msg saying that the bbPress theme needs the Twenty Ten theme installed.

BTW, it makes no difference using Pro Sites to list the bbPress and Twenty Ten theme access to NONE.

I do not wish to provide BP/bbPress themes users. My impression is that bbPress themes are downgraded anyhow and should not be used.

How do I get rid of this theme?
