Lifecycle state changes back to the first step after close

Hi, In my workflow , in the last state I promote my lifecycle to close, but after completing that task, under State I can see the first step of life cycle shown although I am on the last stage of WF. For example LF : New--> In Work --> Closed In WF on the last node I promote the LF  from In Work to closed. What I see after that for this Item is that the state of LF is the first step "New". what do I do wrong?
