I'm not an ANNIE collaborator, but I found this issue in MicroBooNE and saw it also exists here after some googling.
@nitish-nayak and I found an issue that causes the GReWeightResonanceDecay calculator to be applied twice, leading to squared weights for the BR1gamma, BR1eta, and Theta_Delta2Npi knobs. This was recently fixed in GENIE, described here.
