I realized that I have 
#+BEGIN: clocktable :scope subtree :maxlevel 2

While you have

#+BEGIN: clocktable :scope file :maxlevel 2

But I don't know where shall I change the setting, the documentation of 

,----
| org-clock-report (found in org-mode-map), which
| is an autoloaded interactive compiled Lisp function in ‘org-clock.el’.
| 
| It is bound to H-r.
| 
| (org-clock-report &optional ARG)
| 
| Update or create a table containing a report about clocked time.
| 
| If point is inside an existing clocktable block, update it.
| Otherwise, insert a new one.
| 
| The new table inherits its properties from the variable
| ‘org-clock-clocktable-default-properties’.  The scope of the
| clocktable, when not specified in the previous variable, is
| ‘subtree’ when the function is called from within a subtree, and
| ‘file’ elsewhere.
| 
| When called with a prefix argument, move to the first clock table
| in the buffer and update it.
`----

But I don't understand why org assumes that I call that function from a subtree.
