Not seeing the Bone Influence capsule in ToonBoom 8.1

Can’t figure this one out.
When I select the Bone Influence Tool, the blue adjustment “capsule” doesn’t show up.
Anyone had this problem?

By default the Influence is set to Infinite so there is nothing denoting a boundary. If you select the Skeleton Bone in the Timeline and look at the Properties window/box you will see Influence at the bottom. There you can switch to Elliptical if you want to.
