E9 bank reconciliation not posting

In E9 , Bank statement have two currency for reconciliation and one is posted without any issue and other one the menu to post the statement under the actions menu is grayed out. Also edit list of this statement got with nil variance . Again re- do checking & clearing , but no changes in system. Does anyone have any suggestions on reasons why the post statement option is grayed out? Any ideas are greatly appreciated.

Any one can provide a solution?
