Hi @phe0908
Yes, there could be a few reasons for this. Did you run the tutorial’s workflow on the input sample data, or did you do this by hand directly? Maybe try running the workflow to create an “answer key” history to compare to, and you might find where the mixup happened.
If that still produces a problem, it helps to try to reproduce it exactly to sort out where the problem is. If the workflow has some problem, we can follow up to get that fixed and you a workaround.
This was the tutorial, correct?
Which server did you run this at? The URL at the top of your browser window is what we would be interested in. Using one of the “Known Working” servers on the tutorial is usually a good idea. Others can work but maybe the reference data is different, or tool versions are different, and that might not be obvious and cause problems when you are learning.
You can even share back your history that has the output of the workflow run. See → How to get faster help with your question. That share link can be posted back here in the reply. If you had to make any modifications to the workflow when you imported it, you can explain and share that workflow back, too, and we can explain how to fix it up.
Let’s start there! Let us know if you solve this yourself and we can definitely follow up!
