Importing part of deck then again import full deck create duplicate notes

I have used this to test this

  1. Download and import older version of the deck xiehanzi.HSK.3.0_HSK.7-9.apkg
  2. Download and import latest version of the same deck with some updates xiehanzi.HSK.3.0.apkg
  3. But notes in HSK 7-9 duplicated.

It should update the deck instead of adding duplicate note data to the decks.
