Day by Staff View - Stuck in 6 day View

Hi all, 

I wonder if anyone can help please?

We have one main booking page with 5 different services listed within it with their own emails addressed linked to Outlook calendars. In the past few weeks, the main booking calendar has only allowed us to view 6 days at a time, which is almost impossible to view when there are 5 services listed. We have also used 'day by staff' view and been able to scan through one day at a time to easily see what appointment are available and where each day. 

I have tried all of the advice i can find only, cleared cache, flicked between the different views, checked the booking availability - nothing seems to fix it.

Is anyone else having this issue, and can anyone help?

Thank you
