.asmx Service not working when publish for some services

I have a project that needs to integrate with legacy asmx services that contains business logic that I must use. I had problems making use of the channels so were allowed to add attributes to make the services rest.

Now here is the problem, I have tested all the services with post man locally and all calls work perfectly with rest as well as the old application still working. Hosting the web app on my local IIS also works. My problem is that when I publish to the server I have some services saying that [ScriptService] attribute is not there but they are there. Then other services works. What am I missing with IIS or publishing? Here is some Name changed code sections. Had to change due to NDA

//Working Service locally returns xml
[System.Web.Services.WebService(Namespace = "http://TheService.ServiceContracts/2006/09", Name = "MyWorkingService")]
    [System.Web.Script.Services.ScriptService]
    public class MyWorkingService : IMyWorkingService
    {
        [System.ServiceModel.Web.WebInvoke(Method = "POST",
            RequestFormat = System.ServiceModel.Web.WebMessageFormat.Json,
            ResponseFormat = System.ServiceModel.Web.WebMessageFormat.Json,
            UriTemplate = "/PostMethod",
            BodyStyle = System.ServiceModel.Web.WebMessageBodyStyle.Wrapped)]
        [System.Web.Services.WebMethod]
        public string PostMethod(MyPostObjectClass item)
        {
            //Business logic
        }

    }
//Failing Service; locally returns json
    [System.Web.Services.WebService(Namespace = "http://TheService.ServiceContracts/2006/09", Name = "MyFailingService")]
    [System.Web.Script.Services.ScriptService]
    public class MyFailingService : IMyFailingService
    {
        [System.ServiceModel.Web.WebInvoke(Method = "POST",
            RequestFormat = System.ServiceModel.Web.WebMessageFormat.Json,
            ResponseFormat = System.ServiceModel.Web.WebMessageFormat.Json,
        UriTemplate = "/GetDataFromObjectFilters",
            BodyStyle = System.ServiceModel.Web.WebMessageBodyStyle.Wrapped)]
        [System.Web.Services.WebMethod]
        public MyResponseObject GetDataFromObjectFilters(ObjectFilterRequestClass item)
        {
            //Business logic
        }
    }
