Problem between implants and Slaves suppression

[Herebus]

Hi, I come here because I've asked this question on severals Discord without answer. I'm triyng to make a mod which add brain implants who should block SuppressionFall. But when testing my mod, after debugging, it's appear that even with a +100% terror or +100% SuppressionOffset, wich is show on the implant in game, doesn't work, and moreover, seems to not apply (at least for terror) because I've check the slave tab, and it say 0% terror (?).
Am I doing something wrong ?

Thanks for reading me.
