how to exclude in columnview certain subheaders (subsection)

[Uwe Brauer]

Hi 

The following example puzzles me.

* Exclude certain ID
:PROPERTIES:
:COLUMNS:  
:ID: 
:END:




** Group2
   :PROPERTIES:
   :ID:       G1
   :Grp1:     1
   :Gr:       Group-1
   :Usuario1: Antonio
   :Usuario2: Isabel
   :Usuario3: Paula
   :Usuario4: Filipe
   :Start:    <2020-07-26 Sun>
   :End:      <2020-11-22 dom>
   :STATUS:   [X]
   :ST1:      [X]
   :Hoja:     H1
   :Ej:       E1
   :END:

** Group2
   :PROPERTIES:
   :ID:       G2
   :Grp1:     1
   :Gr:       Group-1
   :Usuario1: Juan
   :Usuario2: Eva
   :Usuario3: Paula
   :Usuario4: Albert
   :Start:    <2020-07-26 Sun>
   :End:      <2020-11-22 dom>
   :STATUS:   [X]
   :ST1:      [X]
   :Hoja:     H1
   :Ej:       E1
   :END:

** List of all group members


#+TBLNAME: mitglieder2
#+BEGIN: columnview   :hlines 2 :skip-empty-rows t :indent nil  :ID  "G1"  :format "%5ITEM(Groups) %5Usuario1(Memember) %5Usuario2(Memember) %5Usuario3(Memember) %5Usuario4(Memember)"
| Groups | Memember | Memember | Memember | Memember |
|--------+----------+----------+----------+----------|
| Group2 | Antonio  | Isabel   | Paula    | Filipe   |
|--------+----------+----------+----------+----------|
| Group2 | Juan     | Eva      | Paula    | Albert   |
 #+END


I don't understand why Group 2 is included the ID says "G1" and Group2
has ID "G2"

What do I miss?

Thanks and regards
