Support: Why does 1 of my 4 games count as leave?

[Synapse]

Ok, in my profile its stated that i have played 4 games total for now. but one is counted as leave on the pie graph, while its stated as a scored in the table, now all but one game have been played over 40 mins, the one with 30 mins i lost but was counted as a +1 due to the fact that i left last and was a lose... now I'm wondering why one of the games is counted as leave while in the table its stated as a score (+1, i think)

You recieved -10 for that game because game duration was 3153 seconds and you left the game after 2189 seconds. Due to our scoring rules that is counted as a leave.
Report status "scored" means that the game report meets our scoring system requirments and can be can be processed.
