HUD notes gone?

Spent most of the night multi-tabling, closed everything down, logged back in today and all my HUD notes have vanished. Not talking about the color tags or hand histories, just those little custom notes I’ve written next to players. Tried reloading and restarting the tracker, but nada. These aren’t saved anywhere locally are they, or am I just missing something obvious here?

Bit annoying cause there was some serious gold in there, especially on those guys who call big but fold turn every time. Anyone run into this, or have any clue if there’s a way to recover these notes? Or do I need to start from scratch and just get into the habit of backing everything up myself?
