draftkings voided my golf matchup after one player withdrew but bet slip said action.

so draftkings just voided my head-to-head matchup after one golfer WD’d before the round, but my bet slip said action, not no action. this is confusing because every other book i’ve used only voids if both guys are out, otherwise action means action unless there’s some technicality in the rules nobody reads. is this some standard thing for online books now or are they just picking and choosing when they pay out? feels off since the slip clearly said action, not no action. i guess rules only matter when they want them to.
