Non visible Tabs do not work

System.InvalidOperationException: Unable to set property 'Visible' on object of type 'Radzen.Blazor.RadzenTabsItem'. The error was: Object reference not set to an instance of an object.
 ---> System.NullReferenceException: Object reference not set to an instance of an object.
