UNSOLVED MMM-Calendar in * amount of days incorrect

[ganget]

I have some trouble with the MMM-Calendar issue.

As you can see “Werken Femke” is twice in 7 days. But these two events are on two different days. I believe this only happens when its after midnight but i’m not sure. How can i fix this issue and make the in * amount of days logic again.

Thank you in advance for reading and helping me.
