Constraint - disable and keep transform not responding

Hi , I am trying to disable the constraint and keyframe it in order to leave my mesh in the stage where its at the moment and release it from the constraint.

I get the mesh to stay at the position I want it, but when I move my timeline the mesh jumps to another place. It seems to be the place where the the origin parenting the constraint at the beginning. I am not sure why is happening, since I am pressing the disable and keep transform and keyframing the mesh at the new position.

Anyone experienced this ?
