Hi everybody,
I hope someone can help me, I tried to debug this, but with no luck...

When you make a reservation for a certain day, then click on 'Next month', the calendar shows the current month and the next month on the same screen (see screenshot 1).

This bug seems to be also present in the demo joomla15.demo.artio.cz/en/2-skoda-octavia-combi-2-tdi-1/subject (see screenshot 2).
It is not related to Ajax, since the demo does not use ajax.

It only occurs when you make a reservation, THEN view the month AFTER the reservation date : if you go back and forth, it works, until you view the month AFTER the reservation date.
