Pin Connector Material Properties

I am using a custom material for my pin connectors that has been set up as a custom material. The material values are correct prior to running the analysis, but are changed to 0 or near zero after the analysis is completed. The custom check box is not active so I can't manually enter the material properties.I am using Sw 2013 SP4. Does anyone have an idea as to what is going on?
