I recently got CREV and GTO+ so I don't really have a good grip on how they work just yet. I think I've got the basics however. But I was running a hand earlier and I kept getting different EV results. In the image below it shows AKo, for example, as +1.02. In an earlier calculation it showed it as -0.89. In fact, the first time I ran it, it showed every hand was -EV.

So what am I missing? I'm not sure what I could be doing wrong.

Any help is appreciated.
