Ignore Zero Views Engagements in Path Analyzer

Use Case:

In the Path analyzer, when we select the option “Starting from Engagement”, It gives us a complete list of all the engagements, Including the engagements which were having Zero views or may be never launched.

It would be better UX if they would be excluded from the drop-down list because it simply doesn't make sense to even select them since nobody has ever seen them, probably they were never launched either.
