Animation curves blended with unwanted additive animations

Hi, I am having issues with animation curves, for example, i have a set of curves in my walking animations that are driving foot IK, but for every additive animation it is blending those curves, as if the additive had a zero value, eg if walking was a value of 1.0, after aim offsets i have a 0.5, and i have several layers of additives going on at any given time.
Is there anyway to avoid that? doesn’t seem right having to put a Ik curve for ever additive set to 1. (which that does gives me correct value when using the get curve value node in animinstance) cant seem to find this on docs or other questions.
thanks in advance.

You can set all the curves your animation requires once inside AnimationModifier blueprint and set it for every animation. Advanced Locomotion System plugin used such approach.
