Import CSV DataTable with blueprint nested struct failed

Import CSV datatable with blueprint struct failed when the nested blueprint struct included.
The csv data:

	     Id	Health
Entry1	9	(H=0,M=3)
Entry2	10	(H=0,M=4)
Entry3	11	(H=0,M=5)
Entry4	12	(H=0,M=6)

I think this is because UProperty* UUserDefinedStruct::CustomFindProperty(const FName Name) function does not deal the property’s display name. Is that?
