当我尝试推送到新页面时，出现以下错误。
（我正在使用Xamarin，表格4.6.0.800）

{System.ArgumentException: An element with the key 'NewAccountLogo' already exists in NameScope
Parameter name: name
  at Xamarin.Forms.Internals.NameScope.Xamarin.Forms.Internals.INameScope.RegisterName (System.String name, System.Object scopedElement) [0x0000e] in D:\a\1\s\Xamarin.Forms.Core\Internals\NameScope.cs:21 
  at amici.NewAccount.InitializeComponent () [0x00078] in C:\Users\X\source\repos\amici\amici\amici\obj\Debug\netstandard2.0\NewAccount.xaml.g.cs:46 
  at amici.NewAccount..ctor () [0x0000f] in C:\Users\X\source\repos\amici\amici\amici\NewAccount.xaml.cs:26 
  at amici.Logon+<OnCreateAccountClick>d__3.MoveNext () [0x0002a] in C:\Users\X\source\repos\amici\amici\amici\logon.xaml.cs:119 }

这个错误看起来很直接，所以我回去重命名了元素，然后在我的项目中搜索了相同的名称。（只有一个）。重新编译并再次尝试，相同的消息，但与新的名称？所以我删除了元素，并尝试重新编译并再次尝试，有趣的是，我得到了同样的信息，但是有了下一个元素？所以现在我我想可能是错误信息不太正确或者试图告诉我其他的东西。我只是不明白。下面是我的xaml。
