Zephyr - cycle summary - how to add test cases in Released section

[sacgodbole1974]

In the Zephyr cycle summary there are 2 sections present Unreleased and released.   At this time I can create a cycle under the unreleased section only.  I want to add test cases in the released section but currently three dots not available.  Is there any configuration present to activate three dots to create a cycle in the released section.
