Additional time being blocked before appointment.

I have my Appointments+ synced with Google Calendar.

Whenever I book a time, it blocks out additional time before the appointment, which I don’t want to happen.

For example:

Book 4:00pm, confirmed 4:00pm. However, when I go to my calendar it is blocked from 2:00pm.

I checked my WordPress/Google Calendar timezones and they seem to be correct. What else am I missing?
