Featured Content Items to Display

I increased 5 to 7 but how can I add remaining featured content items. Here 5 tabs are visible even I am increased the items.

The five Custom Features that are defined within the Featured Content Carousel widget are separate from site content that has been marked as Featured. The Custom Features are limited to five, the box highlighted above relates specifically to the site content that has been marked as Featured.

How can I add more than 5 carousel images. Below attachment I can able to add 5 carousel images only. Will you give suggestion on this.

Featuring Content within your community allows more slides to be displayed. Content created within the widget itself is limited to 5 items. 

Is there any way to increase items in same widget. If not how can I increase items in some other widget.
