Buffer time doesn't show up

[awcine]

I'm trying to figure out why bookings doesn't account for my buffer time. See pics. Trying to get a 5 minute buffer between meetings. Any help would be welcome.

@awcine I am able to make it work, can you check the video? 

I guess for that particular service in Availability Options, Scheduling policy you have set the Time increments as 25 min, try changing it to 30 min.

My meetings 45min with 15min buffer: see my screenshots

Looked correct first:

After the first meeting  (13:00) booked, it showed this:

I hope there is a fix?

Thanks
