You are quite right, thanks. That report was checking the place against the whole family record, rather than just the marriage event. So, for example, one of your results was included because a “50th Anniversary” event held in Ontario was included, even though the marriage itself was in the USA.
Now fixed, for next release.
The change can be implemented now by downloading the attached zip folder. Copy it’s content (“functions_resource.php”) to the folder ../kiwitrees/includes/functions/ to replace the existing version.
