Service Information showing wrong service duration timing

Attached is the picture, the service information is showing 10mins. My custom timeslot is 15mins. Is this a bug?

Hi,
The service time-length you entered for the service is 10 mins while your custom timeslots have time-length is 15 mins. You should check your service time-length and just it. It's not error of OS Services Booking.

Yes, but I am using custom time slot, the time slot length field is only applicable for Normal Timeslots. The 10mins seems to be coming from that field. Why does it show the normal timeslots service length when I am using custom time slot ??
