As stated in the title, when I use a mutation to change the values of a column with multiple dropdown values, it clears out the values of a column that has the same dropdown options. I’m using axios.

      query: `mutation ($itemId: Int!, $boardId: Int!, $columnValues: JSON!) {

              change_multiple_column_values (

                item_id: $itemId,

                board_id: $boardId, 

                column_values: $columnValues

             ) {id}

            }`,

      variables: {

        itemId: parseInt(contactId),

        boardId: 1234567,

        columnValues: JSON.stringify({

          // PRE: birth plan (Multiple Choices)

          dropdown06: { labels: preBirthPlan },

          // POST: birth interventions (Multiple Choices)

          dropdown97: { labels: postBirthInterventions },

        }),

      },

    };

    const { data } = await axios.post("https://api.monday.com/v2", body, {

      headers: {

        "Content-Type": "application/json",

        Authorization: process.env.MONDAY_API_KEY,

      },

    });
