Transform not a child ??

Just bought this avatar, trying to rig it to a humanoid however I’m getting this problem stopping it from doing that.

Left Foot Transform ‘Foot.L’ is not a child of Left Lower Leg Transform ‘Leg_2.l’.
I go into it and change the child so everything is green and ay ok, however when pressing apply then done, it seems it doesn’t update and goes back to it’s default set?
