Interesting. I did some experiments and confirmed that custom columns that no longer exist are not removed. I can understand what is happening: calibre is updating the list of columns instead of replacing it.
You can work around this problem by using the "Modify Epub" *plugin* to remove all calibre-specific metadata, then use Embed or Polish to put it back in.
Tomorrow I will look at fixing calibre. Kovid might have had a reason for this and I need to check with him before running amok.
