[Zope] IEMethod and Owner permissions

Hello I'm using the IEMethod product installed on Zope 2.1.6 In a folder object's security tab, I have set Owner to be allowed to change IEMethod, but an ACL User in that folder (being Owner) can't. When logged in as this Owner user, I can't change (File) my changes in the IEMethod. Any similar security setting for DTML Documents or DTML Methods works with this logic. Ideas? Solutions?
