I tried it on single player with different blocks above. It all converted into mud.

Might it be possible, that it was just a small patch of jungle edge (which consists of dirt and podzol) or someone placed a piece of dirt, which was overgrown by grass then (e.g. use seeds)?

I use NEI with the tooltips "on", so you can check each block you look at.
