"Problem" related list on the Incident form is a relationship related list that is driving this behavior and setting the Parent in Problem record when selected. Check for the related list record on Incident form in the Default view.In that record, there is "problem.parent" related list entry.By default, there are no conditions created in this related list entry and that is why all the Problem records are available while selecting the problem.ResolutionIf a user wants only problems without a parent should be available for selection while adding a Problem to the Incident record, then they might need to add filter condition like "Parent is not empty" in "problem.parent" related list entry.
