Appointments+ and qTranslate issues

Hello
I'm using the appointments+ plugin along with qTranslate plugin and I came across some issues and hope someone can help me.
My site: http://v-designs.ch/simair/en/termin-buchen/
The description which is loaded under the services/service-providers isn't loaded in the currently present language. Also when clicking on "next month" the current language isn't part of the permalink. Any suggestions how I can change this?
Thanks in advance!
