The average GAP for every lap disappear immediately after editing - changing type of intervals. But in GC Android it´s OK, so the BUG is only in GC Web.
That’s annoying but what’s even worse is Garmin GAP is useless imo. Like if I run a lap that’s net uphill or net zero elevation change, Garmin will sometimes calculate a GAP that’s slower than actual pace, which is clearly impossible.
