Thank You for contacting Telerik. I hope you don’t mind I converted your support ticket into a public forum post so that the rest of our customers can benefit from our response.
From what I understand, during the recording of tests, Elements Explorer lists duplicate entries for the same elements with slightly different names, making it difficult to manage test cases on an ongoing basis.
To prevent duplication, Test Studio allows you to change the “Elements Page Compare Mode” to the “FullPath” value, as opposed to “FullPathandQuery”. Our Support Site has a great article explaining why this is necessary and a quick way to resolve it. For a full explanation, including step by step instructions you can view the Merge Page Nodes section of our documentation.
