Instead of my story branching out there is an X.

Question

It is hard to explain so please look at the image.

On the "Leave him." option I have put [[Ending]] but it puts this X instead of creating another place to write.

Please help.

Answer 1

That means there's no passage titled "Ending"

There's an "+ passage" button on the bottom right

Comments

It is supposed to automatically create the passages.

Sometimes it doesn't, especially when there's been editing to things, as I have found. The easiest way is indeed the way you're saying it works, but the sure fire way is to add a passage and title it what you want it to be.

Answer 2

This is a known bug in the 2.1.3 release. 

It will presumably be ironed out in the next release.
