I can't say I have mainly because when I decon its a pile at a time so I don't pay attention.
Now have you bugged this in game, my reason for asking is the Mod's rarely look at this forum as its for discussing Crafting etc and not for reporting faults so the chances of them looking are slim.
When you deconstructed the glyphs, did you get any parts from it? There was a bug a while ago, that when a bugged glpyh was deconstructed and it gave no parts, it also gave no exp.
This was caused by the glyphs not giving Potency runes.
If you got a Essence or Aspect rune, you got exp tho but if your 'random roll' was for a potency rune, you got no exp and no rune.
