Custom Markers work in a different way as the standard markers. The problem you are facing is a known issue, The best way to deal with this are as follows:

• Make sure that the image for the custom marker is symmetrical and id perfectly aligned to the anchor.
• The info window should also be similarly aligned symmetrically in the center of the marker, else it will look ugly. Please note that the Custom marker icons often require a different anchor . For the info window, use a custom info window layout (with a custom background) to align it correctly to the marker.
