Glyph won't changed until agl

  • Hello, I made my own custom lists of glyphContructions like the one already in robofab ( For example I have uni021B: t commaaccent.bottom in the list when I run the code everything goes fine, my glyph will be compiled, except the glyph seems to be unchaged… No changed border, no changed header.
    Until: I add the glyphname in fontTools.agl 021B;uni021B;TCOMMA
    Then everything goes like expected.

    Is it really necessary to doe also the agl-thing?
