How to Copy/Paste a cable between projects?

Having an issue:

I have a cable assembly I've created that I want to use in another project that exists in our system...simple enough I just copy (CTRL+C) from one project and paste (CTRL+V) into the other.  I've done this a hundred times in the past with no problem but now it doesn't work anymore...

However now, there's issues all over, hard to see any real pattern but it appears:

any black/white cables turn both conductors to white

any black/white/green cables turn the black conductor white and the white conductor green

Any suggestions?
