In your screenshot Leg_BCK_R_IK
is a child of Foot_BCK_R_IK
. When you use a transform constraint to rotate Foot_BCK_R_IK
, it causes Leg_BCK_R_IK
to move. You don't even need a transform constraint to see this, just rotate Foot_BCK_R_IK
directly.
Look at your constraint order: you apply both IK constraints, then the transform constraint. That is why the IK bones don't point at their targets
you've used the transform constraint to move the targets after the IK was applied.
You have the transform constraint affecting 2 bones:

I doubt you want it to control Foot_BCK_R
. Also see where I moved the transform constraint in the screenshot? The transform constraint happens first, then the IK constraints. This behaves reasonably.
However, do you even need a transform constraint? You can just rotate Foot_BCK_R_IK
directly.
