The Code Conversion Utility inserted nodes to preserve cluster element names after an Array to Cluster node.
This version of LabVIEW NXG has different naming restrictions for cluster elements. Unnamed cluster elements are not allowed and all cluster elements require a unique name. The Code Conversion Utility inserted nodes to preserve the original cluster element names so that downstream nodes are correct.
No action is required. However, if performance is a concern, consider removing the inserted nodes and updating downstream nodes.
