When my calendar is opened, it shows this "service in client's home". I only take dogs in my own home so what is that about?

It seems that Rover designed the calendars to consistently and uniformly show Services in the client's home on the left, as well for all sitters, which is convenient if sitters change where services offered.
Services in your home is to the right of that in gray text that changes t black when you move mouse over it and click. As long as you update your home calendar, it should not pose an issue because customers clicking your profile only see services offered in your home with your rates.

I noticed yesterday evening that rover updated the system again. I had a problem adjusting a repeat customers rate. Check your profile as the update could have caused a glitch with your calendar. -Kathleen D.
