Multiple movement behaviors bug

I tried to create a path animation - move a paddle ball along a path (8 points).

So I've added 8 "Move -> Movement" behaviors (first one with Tab action, the others I planed to set each one after its predecessor).

This is how it looks:

When I clicked the Manage Action Set - this is what I got:

which is not what I've expected.

Anyway, clicking "change..." on any of the targets generated this error:

An application error occurred while attempting to perform the last action.

Restarting InteractBuilder is recommended.
