pt-mysql-summary semisynchronous informtion is wrong

In a pt-mysql-summary output I see the following the stats section:

Rpl_semi_sync_master_net_avg_wait_time 7
Rpl_semi_sync_master_net_wait_time 1750000000 20000 800000
Rpl_semi_sync_master_net_waits 4000000 45 2250
Rpl_semi_sync_master_no_tx 80
Rpl_semi_sync_master_tx_avg_wait_time 4000
Rpl_semi_sync_master_tx_wait_time 6000000000000 70000000 350000
Rpl_semi_sync_master_tx_waits 22500000 250 600
Rpl_semi_sync_master_wait_pos_backtraverse 900000 10 5
Rpl_semi_sync_master_yes_tx 1750000 20 450

And then in the "Semisynchronous Replication" section they appear empty:

   master semisync status |
       master trace level | 32, net wait (more information about network waits)
master timeout in milliseconds | 604800000
  master waits for slaves | ON
           master clients |
 master net_avg_wait_time |
     master net_wait_time |
         master net_waits |
          master no_times |
             master no_tx |
 master timefunc_failures |
  master tx_avg_wait_time |
      master tx_wait_time |
          master tx_waits |
master wait_pos_backtraverse |
     master wait_sessions |
            master yes_tx |
                    Slave | Disabled

Not sure if they are worthy to be there at all, since we have them in the status, but that's true for other entries in other sections too; In any case: if they are to remain there, they should have proper data :-)
