      if ((tvb_reported_length_remaining(tvb, offset) >= 4) &&
         (((io_data_input->connid_type == ECIDT_O2T) && enip_OTrun_idle) ||
         ((io_data_input->connid_type == ECIDT_T2O) && enip_TOrun_idle)))
      {
         dissect_cip_run_idle(tvb, offset, io_tree);
         offset += 4;
      }

There are two preferences that affect this and the default is to only do one direction:

static gboolean enip_OTrun_idle = TRUE;
static gboolean enip_TOrun_idle = FALSE;

Check the protocol preferences to see if only one is checked.
