Here are a few things to check:
Make sure that the state of the object is set to “Normal”. If it is set to “Default” it will assume the state is was in when the instance was last submitted.
Remember that you can set a series of states of an object based on Role and workflow stage: /Documentation/manual/html/?fa_setting_a_series_of_states_on_.htm.
Finally, if that doesn’t help delete the object (button). You will be shown a message that tells you what other objects have behaviors that reference the deleted object. Then you can figure out what is causing the unwanted change. Remember to un-delete after you have taken a screen shot of the list in the message.
