Opening Stats

I checked the opening stats. One of my least played openings has ben the Anderson. It said I only played it twice, and that I won it both times, with a 100 percent win rate. I researched this opening, and although it looks odd, it is  kind of best for defensive players, and thats how I play best. I actually prefer playing black. Anyway I played it 4 more times, and won 3 out of the 4. This would be 5 out of 6 wins or an 83% win rate. I rechecked the stats and unfortunately it still says 2 wins, at 100 percent win rate. Now I am really doubting the stats. I am really beginning to think that out of the thousands of games I played I must have played it more than twice, even before I saw 2 games played. Does anyone know why the opening stats are inaccurate?

it might be a technical bug and you could reflect it to chess support
