PI Module Database and PISDK: References to Properties and Alias return no reference sporadically

Properties under specific PIUnits will work fine but then under others I will not get any values back. Could there be some sort of corrupt in the module database? I am using an EMDVB interface to create batches in the batch database. I have added some custom properties and alias on top of what the interface is using. In my code I reference those properties when needed. Of course I had no problems in development, but when move onto a clients machine the properties would not always read in properly. 

The code below is used to get all of the values which are then used in a short term cache. 

        For Each piProperty As PIProperty In phaseModule.PIProperties
            Select Case piProperty.Name
                Case "MaterialName"
                    phaseData.materialName = piProperty.Value
                Case "MaterialCode"
                    phaseData.materialCode = piProperty.Value
                Case "EngUnits"
                    phaseData.engUnits = piProperty.Value
            End Select
        Next
