Downloading active listings, not all appear

I am doing a stocktake of my CDs listed on eBay. I followed the instructions and downloaded a report which was supposed to show all my active listings. I was surprised to find that not all of the CDs which are shown as being active on eBay when I click on Active appear in the downloaded report. Is there a limit on the number of items which can be listed in a downloaded report?

 

I have just looked at my Excel database and found that the CDs which do not appear in the downloaded report are all items I listed on 1st October, five days ago.  Is there a waiting period between the time an item is listed and the time it is included in a download?
