Ignition OPC UA Server 'null' Values

Hello,
I am currently experiencing an issue with 'null' values on an Ignition OPCUA Server. The OPCUA Server is connected to a the OPC Tunneler Module. We are receiving values from a classic OPC DA server. When the Value on the OPC DA is "0", the same value on the OPCUA server is "null". Is there a remedy to this? the Tag qualities are good all the way through.
