I am not sure how this is even possible as we are not indexing blocks and the id in the error.  Why are we getting this when its trying to covert it when its a page data object

Content with id '11057' is of type 'Castle.Proxies.RelatedLinksBlockProxy' which does not inherit required type 'EPiServer.Core.PageData'

when i look at the item in the index with 11057, you can see below:

{
    "SearchSubsection$$string": "2015",
    "AlternateTitle$$string": "Get the Facts about the NCLEX-RN",
    "GetTimestamp$$date": "2015-12-09T20:59:33.3387188Z",
    "IsPendingPublish$$bool": false,
    "ContentLink": {
        "IsExternalProvider$$bool": false,
        "WorkID$$number": 0,
        "ID$$number": 11057,
        "$type": "EPiServer.Find.Cms.IndexableContentReference, EPiServer.Find.Cms",
        "___types": [
            "EPiServer.Find.Cms.IndexableContentReference",
            "EPiServer.Core.ContentReference",
            "System.Object",
            "System.IComparable",
    REMOVED FOR SHORTING UNECESSARY ITEMS
    "SetChangedOnPublish$$bool": false,
    "_TypeDisplayName": "News Item",
    "MasterLanguageBranch$$string": "en",
    "$type": "CNO.Models.Pages.NewsItemPage, CNO",

Any help would be appreciated.
