I followed a short tutorial to find duplicate String. I open Java Basics -> Group By Value and insert "java.lang.String".
The result is only a single line:
String Value| Objects | Shallow Heap | Avg. Retained Size | Retained Heap
-----------------------------------------------------------------------------
| 6.682.585 | 106.921.360 | 61 | >= 411.154.232
-----------------------------------------------------------------------------
I expected the top 20 values to be shown. Does it mean I do not have any duplicate values in more than 6.5 million Strings?

That line appears to show that you have 6682585 strings with no value, and that you have no other sorts of string.
Is this an IBM Portable Heap Dump (PHD) file? These do not contain primitive field or primitive array contents, so no no string values can be shown.
If it is a different heap dump then please let us know the JVM version which generated the dump and show the inspector view when selecting a String object so we can see the field values.
