count is 15 only shows 9 items though

Trying to figure-out why the count is 15, but only 9 items are displayed...

  using (AgentFormsDataContext dc = new AgentFormsDataContext())
            {

                allForms = dc.AgentFormList_Get(AssetID, AssetSID).ToList<AgentFormList_GetResult>();
                forms = allForms.FindAll(item => item.Active == true || item.Active == null);
                formsHistory = allForms.FindAll(item => item.AcceptanceReqd == true && item.ActionDate != null);
            }

Select allOpen in new window

forms count is 15 shows 9  (incorrect)
formsHistory count is 8 shows 8  (correct)
