Likely the problem is you killed that first steel watch aligning yourself against Gortash, unlike the rest of the fist they remember your crimes and will persist in accosting you effectively forcing you to fight every fist and steel watch that sees you until you deal with the factory. Also looting guards and civilians is a crime so don't been seen doing it.

It happened to me too after killing a steel watch which also triggered orin starting disable the steel watch quest
