Cumulative and daily minutes wrong

Best stats.fm team

The “daily” and the “cumulative” graphs have numbers on the left which indicate how higher, how more minutes you've listened.

But on some days, i listened more than 500 minutes but the peak is still under 500.

The same with the cumulative graph because this year, i've listened 30.000 minutes to music but the numbers on the left say that I listened less than 10.000 minutes.

Kind regards, I hope you could fix this.
