Problem trying to get data to Qlik Sense from Clickhouse through ODBC connector.

When load is finished without error, the number of rows doesn't match the table rows number in database (not all rows are loaded), also getting different number of records each load. (only 75-85% of rows loaded)
ODBC version - Release 1.2.1.20220905
ClickHouse - 24.3.2.23
table DDL:

CREATE TABLE db_name.table_name
(
    `id` UInt64,
    `title` Nullable(String),
    `item_price` Nullable(Float64),
    `description` Nullable(String),
    `image_url` Nullable(String),
    `product_url` Nullable(String),
    `manufacturer_code` Nullable(String),
    `article_number` Nullable(String),
    `sale_price` Nullable(Float64),
    `manufacturer` Nullable(String),
    `short_message` Nullable(String),
    `specs` Nullable(String),
    `brand` Nullable(String),
    `categories` Nullable(String),    
    `margin_priority` Nullable(String),
    `eans_values` Nullable(String),
    `updated_at` DateTime
)
ENGINE = MergeTree
PARTITION BY toYYYYMM(updated_at)
ORDER BY id
SETTINGS index_granularity = 8192;
