GCE Vectrex Overlay Misalignment

Hi All - I’m looking for some help here, I’ve tried everything to get these vectrex overlays to align with the vectrex lines on the screen but nothing i try seems to work, when i adjust the X,Y in video settings using the custom video settings it simply moves both the overlay and the lines and i cannot make them aligned. Not sure where I’m going wrong here. can someone help? 20210326045724
