data discrepancy between api and klaviyo dashboard

hi, i’m using metric aggregates endpoint to get subscribed and unsubscribed numbers like this

const start_date = '2023-07-01';
const end_date = '2023-08-01';

const total_subbed_to_list = await axios.request({
  method: 'POST',
  baseURL: 'https://a.klaviyo.com/api/metric-aggregates',
  headers: {
    accept: 'application/json',
    revision: '2023-06-15',
    Authorization: `Klaviyo-API-Key ${api_key}`,
  },
  data: {
    data: {
      type: 'metric-aggregate',
      attributes: {
        metric_id: metricId['Subscribed to List'],
        interval: 'month',
        measurements: ['count'],
        filter: [`greater-or-equal(datetime,${start_date})`, `less-than(datetime,${end_date})`],
        page_size: 10000,
        timezone: 'UTC',
      },
    },
  },
});

similarly i’m getting it for ‘Unsubscribed’ and ‘Unsubscribed from List’

here are the results i’m getting from the api for july

"total_subbed_to_list": 104,

"total_unsubbed": 164,

"total_unsubbed_from_list": 0

but on the dashboard it shows different numbers. for unsubscribed, the number is way off, 164 from api compared to 18 in the dashboard

does anyone know what’s going on? is this a known issue or am i doing something wrong?
