Tree top tips? (Speedtree)

Hello! I finally got something to look decent-ish in speedtree, but I’m struggling to get the tops to look alright. The modeler filters out the top and refuses to evenly place things like branches near it. I managed to force it to add some to the absolute top of it with another level of branches, but there’s still an ugly gap. Is there any way to make it stop filtering out placement at extremes?

Do you have any tips for how you apply modifiers to make them look better?
