Hi, I have a site using 7.3.0 and I am trying to upgrade it to 7.4.1 and Im getting this issue:

Exception information: Exception type: InvalidOperationException Exception message: The pre-application start initialization method Install on type Umbraco.ModelsBuilder.Umbraco.LiveModelsProviderModule threw an exception with the following error message: Unrecognized attribute 'disableAlternativeTemplates'. Note that attribute names are case-sensitive.
