state is not changing from backend

Hello Jevents Team...

I am using

PHP Version : 5.3.10-1ubuntu3.8

Joomla : 2.5.13

component_com_jevents : 3.1.6

component_com_jce : 2.3.3.2

module_mod_jevents_cal : 3.1.6

module_mod_jevents_filter : 3.1.6

module_mod_jevents_latest : 3.1.6

module_mod_jevents_legend : 3.1.6

module_mod_jevents_notify : 3.0.4

module_mod_jevents_switchview : 3.1.6

plugin_finder_jevents : 3.1.5 (not enabled)

plugin_jevents_jevanonuser : 3.0.3

plugin_jevents_jevcustomfields : 3.1.4

plugin_jevents_jevnotify : 3.0.4

plugin_search_eventsearch : 3.1.5

My problem is that whenever i try to add/edit events from backend(admin),every fields get edited/updated, except one field i.e. State field. State doesn't change. In case of adding new events it always take "published" state and in case of editing events it takes already selected state.
State is changing from the list of events by clicking on the red/green state button...but not from editing a list form.

plz help
