I need help with understanding the calendar? I am new with Rover, Who can help me?

Hi, I am new with Rover and i am struggling to understand about the calendar works? I've tried to call the Rover support number and i left them an email but i am thinking they may be busy but i seen this FA&Q page and i am wanting to ask it on here in case anyone could help me out.

I am trying to understand the calendar where you book. Okay so i get how to set the days but i am confused on the spaces part? Like is it showing how many dogs i can walk or visit in a day or is that like with the same dog that day? for an example : say a client wants me to walk there dog on Monday and i have the space set for 2 walks that day, do i give that dog 2 walks that day or one walk for that dog that day and the other walk is for the other dog thats booked that day? same as with the dog visiting, i have it set for 3 visits, do i visit that dog 3 times in one day or how does it work? Let me know, i don't want to confuse myself or have any clients upset or you know lol!
