Some kinds are more likely to crack than others.
Circular cracks near the stems tend to be genetic.
Cracks for stem to blossom end often occur with erratic water supply which can occur even with soakers.

Cut back on watering , and yes some varieties are more prone to cracking

Also, if they are cracking after color break, why not pick them soon after color break and let them ripen inside. This way there will be no spoilage and maybe tastier (less water).
