[1.7.10] blockGlass oddities

[Kiefy]

1. If I put Minecraft Glass into the convertor, it will offer me 11 types of glass:
   
   so I choose one, say EnderIO's 'Quite Clear Glass', but instead I drag out ExtraUtilities 'Thickened Glass', so then I click ExtraUtilities 'Thickened Glass' and instead get ExtraUtilities 'Edged Glass', and so on. it's like a secret codewhere everything is something else.

2. After changing from vanilla glass, it then only shows 10 types of glass, so I can't go back to Vanilla basic glass.
   
   Except for Black Stained glass?

3. NEI shows over 30 different glass blocks with the exact oreDict ID 'blockGlass'. Not counting 'blockGlassHardened' etc. Why does the convertor only show 10/11 of them?
