edit email action on schedule search says page not found

Hi All, I have few schedule searches under an app whose permission is set as "not visible" ( visible=NO ) in SPLUNK Search Head and for these schedule searches when I click on edit email action hyper link available on schedule search edit page, it opens a new page and says page not available . The same schedule search if I move to some other app which is visible, the edit email action page opens perfectly fine . Does anyone know is this the expected behavior ( not expecting ) or something is wrong in my instance ? . I found this problem on 6.3.1 version of SPLUNK and not sure if it was exist in previous version of has been fixed in recent versions . Thanks !!
