For something to show in that table which has the selector, it must match at least 1 class and 1 race, or a component script hides it. Since neither of the "all characters" FCBs need a selection, there has been no issue with them being hidden here. I think you'll need to special case this particular FCB to unhide itself. Add this eval script to your FCB

if (field[fcCount].value <> 0) then
perform delete[Hide.FavClass]
perform hero.assign[Hero.FavClList]
endif
