List - missing index?

Hello @all,
i am missing index number [7] :smiley:
how is this even possible?

You’re missing branch 0 and 7.

What is the problem?

Can you share the definition?

unfortunately i cannot because of restriction of my work place… but i got through the process and i realised after grouping by key the list shows up strange… so cleaning up the tree worked there ofr me :slight_smile:
