Thanks, that answers one part of my question that was summarily removed (though I received a courteous reply from the support team).
And I am glad everybody else finally got to see that.
Until the fix is in; should we adjust all dates from Geni by one day? And which way? And does it affect dates from other sources?
There is also an issue with the setting out of the names of ladies who have married; not only does Geni use a different notation to many of us
(if Mary Smith marries John Jones I use Mary Jones (born Smith) but they prefer Mary Smith Jones) but it mucks up the names in the tree (neither one nor the other) and I have to correct them. Is that a bug too?
Every extract match process gives you the opportunity to choose the information you would like to copy to your family tree.
Instead of clicking on the generic "Extract all" on the bottom of the page, you can click on the arrows between the match and the data on your tree for each piece of information, and extract those bits of information one by one:
This can be done for the dates, names, etc. That way, you can keep the data that you believe is already correct on your family tree.
