Service Windows

Hi Luca - having some difficulties with the “exact times” service window options. I would like to use exact times for my Meet & Greets, however I would like to limit the service window to be from 10 AM-8PM. Even though I select only the 10 AM and 8 PM slot time in the service window for Meet & Greets, on my booking page it will still show availability starting at 7 AM and ending at 9:30 PM. Unsure if this is a bug or if I’m doing something wrong. Thanks
