Sapling issue

Okay, so I have just started experimenting with the Sapling Addon in Blender and I already have an issue. For some unknown reason, the Shape button is greyed out on the Options menu. And I got no idea why, I really just popped one in and bam. It’s greyed out.

Change the “Settings” from the default “Geometry” to “Branch Splitting”

By default the “Levels” is set to 2, change it to at least 3 or more , that’s the requirement for the Shape button to actually work

Change the “Settings” back to “Geometry”, you will see that now the Shape drop down menu is not grayed anymore and works as it should.

Thank you!!
