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.
