Build in RTC problems on the makerwan1310

Dear forum users

I Have a little problem regarding the build in RTC on the mkrwan1310.

When I set the rtc alarm to go off every 2 minuts it goes off every minute.

And I don't know where the problem would be. So I hope some smart people on here can help?

#include <RTCZero.h>RTCZero rtc;const byte seconds = 0;const byte minute - this is the code.

Thank you in advance and with best regards Ben
