Why am I getting this error when I was trying to Display the target?

Hi there, I loaded a csv file to adobe campaign classic, the settings are shown following:

The file has been uploaded to server as well. Once I finished the workflow design, and when I was trying to display the target in the flow, I always get the error: 

Does anyone have any idea why am I getting this error? Thanks so much!

Hello @KevinWang_ 

To make this work, you will have to check in workflow properties which says "Keep the result of interim populations between two executions".

By Default, Adobe deleted the temporary tables once the workflow is finished. To keep those temporary tables you will have to select the checkbox.

Let me know if that helps.
