Are you sure they are just multiplied by 100? That's not the case in my platforms - MT5 volumes differ somewhat from MT4 even if you account for some multiplier.
You can check if some bar indeed should have been colored by wasn't by looking at the volume for each of the preceding candle, writing it down, and then calculation its average multiplied by 1.5. Then, check it against the volume of the candle in question.
