SQL Analysis Services JDBC Driver detects all column as VARCHAR

Hi Cdata folks,

Cdata driver latest version v23

Weird thing is that SQL Analysis Services JDBC Driver detects all column as VARCHAR no matter what type of the model column:

This is the model in Visual Studio:
 

Before importing, the data type is also detected correctly in Visual Studio:
 

But in meta data, type for all columns is VARCHAR
This is how I get the metadata:

Connection conn = DriverManager.getConnection("jdbc:ssas:AuthScheme=BASIC;User=user;Password=pwd;URL=http://HOST/OLAP/msmdpump.dll;");
Statement stat = conn.createStatement();
DatabaseMetaData databaseMetaData = conn.getMetaData();

        try(ResultSet columns = databaseMetaData.getColumns("TabularProject3","Model","Table","integer")){
            while(columns.next()) {
                System.out.println(columns.getString("COLUMN_NAME"));
                System.out.println(columns.getString("DATA_TYPE"));
                System.out.println(columns.getString("COLUMN_SIZE"));
                System.out.println(columns.getString("TYPE_NAME"));
            }
        }

In document, there is no other connection string param that I think can apply to change how Cdata driver detects column type.Am I missing anything else?
