错误代码 1292 截断不正确的 DOUBLE 值 Mysql

我不确定这是什么错误！

#1292 - Truncated incorrect DOUBLE value: 

我没有双值字段或数据！

我浪费了整整一个小时想弄明白这件事！

这是我的问题

INSERT INTO call_managment_system.contact_numbers 
    (account_id, contact_number, contact_extension, main_number, created_by)
SELECT
    ac.account_id,
    REPLACE(REPLACE(REPLACE(REPLACE(ta.phone_number, '-', ''), ' ', ''), ')', ''),'(','') AS Phone,
    IFNULL(ta.ext, '') AS extention,
    '1' AS MainNumber,
    '2' AS created_by
FROM 
    cvsnumbers AS ta
    INNER JOIN accounts AS ac ON ac.company_code = ta.company_code
WHERE 
    LENGTH(REPLACE(REPLACE(REPLACE(REPLACE(ta.phone_number, '-', ''), ' ', ''), ')', ''),'(','') ) = 10

下面是我的show create table，它将显示结果
