Previous Action tab has been removed. It is not needed- the top action in an action sequence happens first and so forth.
Try to make the Pre Flop action sequence in the following manner:
- for the first action select 'Post Big Blind' and 'Player had to be the HERO'
- if you want to remove limps then create another action and select 'Call' and 'Action had to NOT happen'
- for the final action select 'Raise', 'Player had to be the note recipient' and choose Small Blind under Position dropdown menu
Note that there is a problem with the latest version - if you're going to be editing a note and not creating a new one, the changes won't be saved unless you also edit the note's name.
I've also attached this definition here. You can import it and check if you still get successes that you shouldn't get.
