Date mismatch when importing files in Library

Question

I am importing files in my Aperture Library using:
1/ Referenced Files,
2/ renaming my files with the following preset: <Custom Name>_Year of picture.Month of picture.Day of picture_Counter, and
3/ asking Aperture to copy the Master file into folder using the Year>Month hierarchy.
There are series of pictures which a) have been taken during the same event, b) with the same camera, with c) apparently all correct Metadata, for which I will end up with:
A> Pictures correctly renamed and stored; and also
B> Pictures renamed as of January 1st 2001, and stored in the folder 2001>01, while the metadata states the correct date, e.g. not 2001, but say September 2008.
Please help!!!
Thanks

Hi there....  thanks for your response.  I hadn't ticked "show the import dialogue".  When I did though I noticed that the box "Do Not Import Suspected Duplicates" was ticked in the Dialogue.  Unchecking that & then waiting for all of the images to load in the dialogue window (I have 115,000 images on the drive) seems to have solved the problem.  At least 98 3/4% anyway.  There's still a slight discrepancy in numbers between the catalogues on both my home & my work computers, but this is down to only 5 or so across various folders.  I can't explain why that would be.  There seems to be lots of other weird things going on which leads me to suspect LR5 is not playing nicely with Mavericks.  it's frustrating because up until now I've found Lightroom to be 100% reliable, but I'm now feeling like I need to double check every import & export.  if it continues it may be the catalyst to make me finally jump to Capture One.  Anyway, thanks again for your reply.
