Title: Entry list field get duplicated entries from specific section
ThreadText: # Entry list field get duplicated entries from specific section
  
  (Asked by: username_0 on 2021-03-30)
  
  I have some weird behavior when I have an entry list field (in a super table, but I get the same behavior from the native entry list field type).
  
  When I select an entry from a certain section, it will populate 2(!) entries in that list, which point to the same entry after save. It looks correct, after I selected the entry, but as soon as I save the entry which contain the list, it gets duplicated?

  It only affects a single, specific section, entries from any other section is fine.
  
  Where to even start trouble-shooting?
