Huge peak of refunds in only one hour (Septmeber 27, 2020, 4 a.m.)?

I had tons of refunds in only one hour today in the app store connect trends sales data. So many in only this one hour like all the last months together!

Is anybody experiencing the same issue or had such a peak in refunds?

Is it possible this can be an error in the data?

Thanks for all your help!
