Updating Related Users (Array of Guids) doesn't show in

Hello all,

I have the below code sample attaching users to a company:

 protected DynamicContent AddUserToCompany(Guid userId, Type companyType)
       
            var manger = DynamicModuleManager.GetManager();

            var identity = ClaimsManager.GetCurrentIdentity();
            DynamicContent companyItem = manger.GetDataItems(companyType)
                        .Where(x => x.Status == Telerik.Sitefinity.GenericContent.Model.ContentLifecycleStatus.Live)
                        .Where(x => x.GetValue<Guid[]>("RelatedUsers").Contains(identity.UserId)).First();

            List<Guid> users = companyItem.GetValue<Guid[]>("RelatedUsers").ToList();
            users.Add(userId);

            companyItem.SetValue("RelatedUsers", users.ToArray());
            manger.Provider.SuppressSecurityChecks = true;
            companyItem.SetWorkflowStatus(manger.Provider.ApplicationName, "Published");
            manger.SaveChanges();
            manger.Provider.SuppressSecurityChecks = false;

            DynamicContent companyItem2 = manger.GetDataItems(companyType)
                        .Where(x => x.Status == Telerik.Sitefinity.GenericContent.Model.ContentLifecycleStatus.Live)
                        .Where(x => x.GetValue<Guid[]>("RelatedUsers").Contains(identity.UserId)).First();
            //need after this for stuff
            return companyItem2;
       

The code saves fine and I can see the changed list programmatically, however the Dynamic content backend UI does not show the added user. It's setup as an array of GUIDs selecting users.
