Pyramid set scheme gives too many reps

When setting an exercise to a pyramid scheme, the reps get ridiculously high. Example, when I tried setting deadlifts, where I'm lifting 300+ pounds, my very first set was 34 reps.  For incline press, where I'm doing over 150 pounds, my first set was 66 reps!  I changed the rep range to 3-5 which helped, but my first set was still 28 reps, which is entirely too many.  If you set a rep range, say 5-15, the app should keep you within that range. First set - w weight at 15 reps, x weight at 12 reps, y weight at 8 reps, z weight at 5 reps.  Reverse pyramid scheme is a little better but still gives higher reps well outside the range. This should be fixed.
