Appointments page starts at date in the past

I have an appointments+ page http://www.lottevesterli.com/booking/
A partner has linked to my page and has seemingly picked up a URL for a specific week. He is sending people to http://www.lottevesterli.com/booking/?wcalendar=1527191170#app_schedule
That page shows a time in the past.
Two questions:
1) What does the wcalendar link mean? I haven't been able to find any documentation
2) Is there a way to redirect people hitting the wcalendar link to the general /booking/ page so they end up at the current week?
Best regards
