Clicking on wrong element

I have a Java Swing Desktop Application. I’m using Robot Framework SwingLibrary to automate the desktop app. I have an usecase where I need to select ‘item x’ from Popup menu. Here is my keyword:
‘SwingLibrary.Select From Popup Menu popuppanel Select|Mode’

This keyword works fine in most of the windows test machines. But it fails in one of the windows test machines where it always clicks ‘item x-1’ instead of ‘item x’. It appears that Jemmy is using (x,y) coordinates to select items instead of selecting as objects.

I tried changing the zoom settings of the desktop-app, display resolution of the OS but nothing seems to work.

Is there other way to operate the popupmenu apart from the keywords provided at https://robotframework.org/SwingLibrary. For eg., in web applications we can use Jquery executor to operate directly on the DOM. Is there a similar way to access the popup menu items in Swing Library? Or are there better options?
