Help with highlight screen element

Hi Guys!!!
I am trying to capture screen and highlight the element but getting a strange problem. When i am running the program, it is highlighting on the program workflow and not the screen element. what could go wrong.iam attaching the window and then using find children activity, all the selectors are correct, when i test highlight them individaully they highlight correct window. but when i run the workflow, the highlight activity is highlighting my workflow.

Please advise.
