I have an org file, about 3k lines with nested headings and property 
drawers.

org-update-dblock on this line inserts a table but only yields a subset 
of the actual headings:

#+BEGIN: columnview :hlines 1 :id bc3cd73e-bb35-46ac-8ab3-3e8bc33be9d1 
:maxlevel 3 :format "%50ITEM(Box) %TODO %TAGS %batch %hwversion 
%ausgeliefert %reinigungsmittel %evaporator_sensor_defekt 
%neuer_innenlüfter %med_netzteil %os"

Whereas this line works:

#+BEGIN: columnview :hlines 1 :id bc3cd73e-bb35-46ac-8ab3-3e8bc33be9d1 
:maxlevel 3 :format "%50ITEM(Box) %TODO %TAGS %batch %hwversion 
%ausgeliefert %reinigungsmittel %evaporator_sensor_defekt 
%neuer_innenlüfter %med_netzteil"

The only difference is that the first version includes 11 (or more) 
fields and the second version only includes 10 fields.

Also, when I repeat org-update-dblock, it yields different results every 
other time and the table is slowly growing, see attached screenshots. I 
also noticed that org-update-dblock seems to randomly add trailing 
whitespaces to headings or lines like ":END:"

The structure of the org file is attached. I tried for two hours to 
provide a minimal example org file but – like randomly – when I shorten 
the file radically or remove fields from the colmunview it works. I 
can't figure out what exactly makes org mode struggling.

Even if I delete all content in the file where lines do not start with 
regex /^\*/ or /^:[a-zA-Z]/, the inserted table is incomplete.

Can someone help to debug this further?
