In Sitefinity, if you have more than one of the same reusable content widgets on the page, the details of that item will duplicate for every widget instance once it is selected by a site visitor. This is a default setting and can affect widgets like People, Events, Newsroom and Calendars.
For example, if a site builder is displaying the people widget three separate times on a page will cause any selected profile to display on the page 3 separate times as well.
For each widget impacted follow the following process:
The result will be that the widget that is selected by site visitors will be the only one on the page that displays the items detail view.
