Please see your previous post for a recent update. The information requested there may also be helpful in this instance, in addition to a Jing video showing the problem. The test failure log you attached does not seem to include the drop down menu selection step. If possible, please provide a copy of the test along with the exported failure details. You mentioned an error. What is the error? If Test Studio is generating an error, please provide us with a copy of the application log. Unfortunately, without further information, we will not be able to diagnose this issue.
