Montage Branch Points - Where are they?

I’m trying to figure out how to access the Branch Points in Animation Montages. Having read through all the documentation and watched tutorial videos it sounds simple enough…yet I cannot find away to insert Branch Points.

Basically I do not see that 4th slot bar in UE4 4.9 where branch points are placed in the Animation Montage as shown in tutorials, only 3 slots are appearing (montage section name, anim slot, anim slot).

Where is that 4th slot? Has the workflow changed since the documentation was written or am I missing something?
