I tried to reproduce the behavior you describe with both two Excel data sources and two SQL databases but unfortunately I was not able to. Please let me know what is the version of Test Studio you are using currently? If it is not the latest official (R2 2016.630.1), please upgrade to it and let me know if you are still facing the same issue.
Please record a short video demonstrating the observed behavior in case it still encounters. You could use Jing
as an easy to share online video recorder.
Thank you and I hope to hear from you soon!
