It seems like the fb ad manager by 4 hr affiliate has the tendency to create 1 less ad. I launched fb ad manager on a campaign that has 12 ads but only 11 were created. So, I deleted the campaign and tried again... several times. Nothing changed except that each time I launch the campaign, a different ad "disappeared". Is there a bug in the tool or something? How can it be fixed? I know the other alternative is to manual create & submit the missing ad but this is gonna be tedious as I've several campaigns but if there's really no way around this, I guess I've no choice.
