Component Remover failing to remove "Unknown" packages on 8.1 Update install.wim

[goscuter1]

Actually, it appears to be removing the packages only to parse them straight back. 

I can't make sense of these "Unknown" packages either; they don't appear to be anything like the lists of removed components being posted on MSDN or MDL forums, and don't correlate with the packages Technet lists for Win 8. 

I'm trying a few other methods to remove them but would this be a Component Remover bug or a problem with corruption in my system?
