Hello @LHD
Thank you for reaching out to the Community regarding your issue, although I am sorry to hear that you are experiencing issues with the gains estimator. I apologized you have not received a response yet as I do not no much about the tool. That being said in this case I believe it would help to get a better idea of the picture if we could get a screenshot of what exactly is happening. I'll leave steps down below.

Once we get the chance please let us know more and we'll see what we're able to find out.
Thanks,
Quicken Francisco
