The Workbench integrated Ansys nCode DesignLife systems are designed to always read the material information from Engineering Data when a solve request is issued from within DesignLife, so any material changes made within the DL UI will be overwritten. You need to "break" the link to WB to enable DsignLife to use material data defined within the DL UI. This behavior is explained in the Intro to Ansys nCode DesignLife training course.
