as per report's subject "installation software sites".
This is still a little ambiguous in the context of the issue because the terms : Install, Software are used in both places I'm thinking of and I can't find the exact wording you've mentioned in either of them.
One place those update sites were show is from Help -> Install New Software.. . I would refer to this page as the Install Wizard. The Combo box at the very top should no longer have those confusing entries displayed. If they still show up here, then my previous fix somehow didn't resolve your case and I would need to investigate this.
From the Install Wizard, immediately below the combo box, there is a link named "Available Software Sites". This opens up the "Available Software Sites" preference page, which is located under "Install/Update" category of the workspace preferences (Window -> Preferences). This page would still be displaying all those entries. I'll have to look into how to hide the entries from this page so I'm happy to keep this open to fix that issue as well.
