[Orgmode] struggling with simple indentation

[Rainer Stengele]

Dear all,

I am struggling with a simple indentation problem.

Having this: (1)
====================================================================

***** test
      - indented
line
^

point at "^" and pressing TAB results in:


***** test
      - indented
      line
      ^
====================================================================

Having this: (2)

***** test
      - indented
      - indented
line
^

point at "^" and pressing TAB results in:


***** test
      - indented
      - indented
line
^

====================================================================

I want to consistently indent lines like in case (1).
Why does org not indent in case (2)
How can I change this behavior? Is it a config issue?

I could not find a variable where I could adapt the indentation behavior.

Best
Rainer
