@Leeann, for the Vision RPA behaviour you are seeing, I recommend switching from “Element description” to the new “Element text” selection type within the Vision RPA Wrk Actions. This option tends to be more reliable and reduce false positives when you are targeting on-screen text.
Regarding the CSS selector reporting success without actually triggering a click, the element you selected #start_over appears to be a list item (<li>), which is not directly clickable. Updating your selector to #start_over a will target the link inside that list item and should allow the browser to execute the click event correctly.
