As far as I know, that is the result of saving as an .EXR. I have found the same thing when opening in Photoshop, all the layers are jumbled, and I have had to re-arrange them every time…
I don’t know if it will run or help as I haven’t tried it for 4. XX
But it is a time saver ( not sure about the extra nodes between input and output, and whether it would work with them connected…) adding a 1-click connection with the EXR-IO output node, may work better…
