In your Spoor configuration, under Tracking: ensure Course completion required is checked and that Assessment pass required is unchecked.

It would also more typical in SCORM to set Tracking success status to completed when completion has nothing to do with passing or failing the assessment, but that's more a semantic thing really.

(I'm assuming your Authoring tool install is using the default Framework version of v2.x and you haven't manually updated it to v3+ or higher)
