clarification on the SON statistics object

The definition in the wiki is as follows

flat_map<sidechain_type, uint64_t> total_txs_signed; // Lifetime total transactions signed flat_map<sidechain_type, uint64_t> txs_signed; // Transactions signed since the last son payouts

Following is the data from the current docker setup:

unlocked >>> get_object 2.25.7
get_object 2.25.7
[{
    "id": "2.25.7",
    "owner": "1.33.7",
    "total_txs_signed": 0,
    "txs_signed": 4,
    "total_voted_time": 343200,
    "total_downtime": 0,
    "current_interval_downtime": 0,
    "last_down_timestamp": "1970-01-01T00:00:00",
    "last_active_timestamp": "2021-07-17T18:42:04",
    "deregistered_timestamp": "1970-01-01T00:00:00",
    "total_sidechain_txs_reported": 4,
    "sidechain_txs_reported": 4
  }
]
unlocked >>>

As you can see here "total_txs_signed" < "txs_signed". (Note: The setup didn't have any transactions created for a day.)
