All EnumValues properties in the server have empty strings breaking any clients relying on string matching of enumerations:
As per discussion in the OPC-F around OPCFoundation/UA-.NETStandard#3123 that is not recommended when adding EnumValues property to the Enumeration type. It is anyway better to use DataTypeDefinition model as of 1.04 to support better and faster interop as the binary schema type dictionary approach is deprecated for quite a while now.
