That is correct, for what ever reason you never took SP on one of the four pre-off bets, could be a few reasons, there might have been a delay with getting the unmatched bet info back from the API so there was no net as far as BA was concerned, or I can see you placed all 4 bets at the same time so maybe one or more of your take SP conditions stopped the rule from triggering
The log gets re-painted once every second so although all 4 bets and 3 SP appear at 10:03:01 its impossible to say what order all that happened
