Mini Calendar // More than one

On our non-profit site we use three Mini-Calendars for three categories.
At a first glance all seems to be okay. But only first Mini-Calendar works like expected. On the other two (following) Calendars it is not possible to switch a month fowards or backwards.
Our site is in alpha-stadium so you may find it here

Hi Klaus

I'm sorry. At the moment, we can only use one instance of mini calendar on a page. It's not possible to have multiple instances on a page

Thx, this could be a feature request ...

Yes. I agree. Will add it to my todo list and find a way to address it in the future releases

I also need a few calendars on one page. Please solve the problem quickly.
