Desktop Automation - Not able to click or focus on element

Hi All ,

Scenario - Need to click on Button on Desktop screen.
Issue - Used cssSelector which was showing on Jvm-inspector.
At the time of inspecting cssSelector shows only one Element. But through bot it shows two elements (by WebElement List size). When it shows size 2 it tries to click but cursor moves little away from the button.

Sometimes Button clicks and sometimes click happens little away from the button.
