session mode wasn't clicked and cache rebuild didn't fix it, but i noticed that when i hover over the stats it listed me as the player. and going into Edit Hud Profiles shows that indeed all of the stats are set to "Hero Only". I guess this would explain why it resets at the start of every fresh table but I have no idea why all the stats have changed themselves to "Hero Only"...?
manually changing them all back to "Everyone But Hero" appears to have fixed the problem
