Two home pages, cannot delete either one

Could it be a template overriding the main content?

I would say try to narrow down the issue by temporary disabling some/all plugins (make a backup first) and also changing to a different theme.

Btw. Addsense Enabler plugin is seriously outdated. Best not to use plugins for GS 2.03 on GS 3+. I think there are newer plugins that do the same. Also, there's a Multi User 1.9 plugin.
