I'm not sure you do understand to be honest.
You've pointed the OP to the SCORM module twice when it's not a SCORM module issue. The line of text that is left now the OP has removed valuable functionality (completion tracking) is a function of the Topics format, no more no less - it is purely a list of the types of activities and the number of each type, in that Topic, nothing to do with a given activities settings.
Adding custom CSS is not what I would class as a hack but, unless someone can point to a setting I missed in the Topics format, it's the cleanest and safest way I know of to get the OP's desired affect.

Note that the OP's original screenshot is showing the start page of a course but only 1 topic title, there will be multiple topic titles with the "offending" text under each depending on what is in the given topic.
