I have been using uipath since last year to test an application as a case.
After the last update to the version UiPath Community 20.10, when the Uipath tries to validate some objects the lines are not anymore available and just lines are shown.
The same problem happens when the user tries to validate the Selector using the UI Explore.
Open JDK Java 1.8.0-265
This image is when I start to execute the test and there is a table to validate if is visible or not.
