There may be a problem of dependencies at LabVIEW level: check if in the .lvproj of the two Custom Workspace Objects there are items with the same name and change the naming. After this edit, compile again the Custom Workspace Object source distributions.
A suggestion to avoid this problem when developing multiple Custom Workspace Objects is adopting a proper naming convention, by giving a common name space for items of the same project, such as:
- CWO_A_Data_Cluster.ctl for a .ctl defining a Data Cluster for the Custom Workspace Object CWO_A
- CWO_B_Data_Cluster.ctl for a .ctl defining a Data Cluster for the Custom Workspace Object CWO_B
