Scheduling calendar not blocking off times

When I add an appointment to my google calendar it usually updates my scheduler, blocking the time off as unavailable. However, the last 2 times I have gone out of town and blocked off several days together, the times have not been marked unavailable on the scheduler. I've had clients book and then had to reschedule them manually.  How do I fix this?

I ran into this issue as well. Were your events set as all day events?

Acuity has told me it's a problem with Zapier, where I'm creating the events. But I believe it's an Acuity problem.
