If you are firing Spectrum S96, even at 677C you are not really getting a proper tack fuse with only 30mins at the temperature.  The bumps and indentations are probably a result of an incomplete adhesion of the glasses.  Tack fuses normally occur in the 720-760C range.

Don’t rely on the pre-programmed schedules.  Instead look at some of Paul’s here on the site.
