Splunk Predict App works only for my first 50 results

Hello,

I've been testing the Splunk Predict App to do some work on Sentiment Analysis, however, after training some model, and using the guess command to predict sentiment, I noticed it works only for the first 50 events and after that the field I'm saving the predicted variable appears empty.

Is there any limit or parameter that I should add to extend the amount of results it applies to or I'm doing something wrong?

Thanks in advance for your help,

Felipe.
