The deeper hierarchy of the calltree cannot jump to the right place

Hi

When I expand the calltree like
```
+ outer_fun
   + inner1_fun1
     + inner2_fun1a
     + inner2_fun2a
   + inner1_fun2
     + inner2_fun1b
     + inner2_fun2b
```
the `inner2`-functions cannot jump to the right place.

Is there something wrong or I miss? Thanks.
