Automatic? component decomposition

FYI Found some useful info here:
https://forum.glyphsapp.com/t/export-issue-how-many-nodes-are-too-many-nodes/5005/14

@GeorgSeifert “If you set the pixel glyphs to export, the components will not be decomposed and the problem will be gone.”

I set my component glyph to export but it is still being decomposed in the TTF. Any ideas?
