That's the Timeline module.
If you disabled the Timeline module so that the site-wide timeline would not show, and that's the goal, but you still want it on the profiles, what you need to do instead of disabling it is to leave it on but change the Timeline modules index.tpl template to change what it shows or remove links to it if you dont want people going there.
By disabling links to it it still exists but there is no click traffic there.
We have the timeline module enabled but no links to it. If we linked to it from somewhere and wanted people to use it we'd clean up the design. But for us the Forums are more central than the Timeline for this style of site.
