HELP!!! Can't see the closed activities in lead tab or closed/open activities in accounts tab! help!!

I have been in zoho crm working on some issues we were having and fixed them! Yay! But now we can't see closed activities in lead details view or closed/open activities in accounts detail view. I have followed the Manuel and it says it's showing the items according to the edit menu. But is still not visible. Is there another area that I can edit it that I've over looked. I've combed every inch of the customization section.
