Sort of an abberation look if I am correct in saying that? I have attached two snips. One shows a white line and the one around the rock is blue?
Edit forgot it was about that old script
It is the the script, makes the initial selection, leaves a border of semi-transparent pixels which show up with the replacement sky.
You can try adjusting the script feather amount value.
You can try editing the layer mask(s) Filters -> Generic -> erode (or dilate)
a quick example, https://i.imgur.com/AorvMDN.mp4 adjusting the script then using dilate to 'grow' the white part of the mask(s) ...but it all depends on your images and you might need to use a more 'hands-on' method
