The morph target check box isn’t needed. I’ll update that. I think I had previously been testing something with Morphs. That should be left off in this example, unless their is some other mesh that is attached that needs morph options. Just not this instance.
sorry for the confusion with that one. 
One way to check and see where it may be falling to would be to use the viewport there in Persona > Show > Scene Setup > Uncheck Floor and see where the mesh is going. If it’s just hanging or continuing to fall.
In my example as well since I did a little banner type setup I had painted a zero weight on the top most edge. Since this zero weight was there it would act as an anchor to hold the cloth in place. Without any weight I would image it to keep falling.
What is the main purpose for your cloth in this setup? Maybe knowing that I could help provide and example that would more accurately fit than my banner type example. Maybe I should re-title that post to indicate this is more used for a Flag/Banner type situation as well.
