As in the title, the thrust rating should be 20360 LBF. It’s the same as in the E195 (which has the correct rating in Simbrief BTW).
As a consequence of this wrong rating the takeoff perf calculator is e.g. unable to calculate a takeoff for EGLC with the E190 (except for extremely low weights).
EDIT: Source is the internet, e.g. wikipedia site of the E-Jets
EDIT2: Oh and please also change this in the FSS E-190 profile, too
