I have just checked here and I am not seeing this. With the option disabled in Start10 the only things showing on the menu on the left are your pinned items. Are you sure you have not pinned some by mistake?
The easy way to tell is right click then and see if an Unpin from Start (Start10) menu item.
If you continue to have issues can you contact support@stardock.com so they can collect more information. Including a screenshot of it with the recently used apps enabled and disabled would be useful too.
