Hi,
I really hope you have time to look into this further and help us with one answer

We need it for our business and customers see dates in a wrong order. We don't see any place where we can set the order of the days from this event.
Screenshot of mixed up days order:

It sets the following date as first date, while 21-09-2018 was the first date:

So before the second day 5-10-2018, 5-10-2018 was shown instead of 21-9-2019. It looks like a bug, because we use Jevents for years now this way.
If you can login you can see it instantly what's wrong maybe? Login details are in Site Details tab.

The event in the admin is the one from my other screenshot.
Thanks again.
