我如何解决这个问题

ReportProcessingException:报表定义无效。详细信息:报表定义的目标命名空间“”无效,无法升级

我试图将RDLC的标题更改为:

<Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">

但当我构建它时,它将更改或撤消我上次的编辑,并显示如下:

<Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">
