Supertrend contract size is sometimes way too high on backtester

Looking over the list of traded from the back tester I’ve seen some entries that are appear to be way too high. I’ve had to attche the files as .txt because csv and xlsx are not supperted here. I was unable to hightlight what I’m talking about because of the file limitation. I’ve also found the same issue with Ultimate Scalper and a different pair.Please advise as this doesn’t look right. I’m eager to get this bot trading live but would like to know what’s going on here before I do.
Thanks
