next month button returns the same month again


I've got two things, the first one is really important to me.

1. The Next month button doesn't return the next month. It returns the same month. So you are not able to see and book appointments in May or anytime later (it's April now). It's the same for the weekly view, I get the same week returned. The appointments upper limit is still 365 days. What do I have to do to change this?

2. Is it possible to add a proper Paypal button when checking out instead of the not so much visible "Please click here to confirm this appointment"? If so, is it possible to skip the next step where you have to confirm "Please confirm $x for xy appointment" and go straight to the Paypal login page instead?

Thanks everyone for helping.

Best, Anja
