If you use the "Re-activate download link, re-send email" function in your Seller Admin, that will simply reset the expiration settings on the buyer's original link and (optionally) resend another copy of their thank-you email(s) with a link to reach their download page(s). Any download attempts made on the original or re-activated link would be logged for their original order in your Transaction Log.
If you use the "Send free download link" function in your Seller Admin to send a new link as a replacement for the original link purchased, attempts made on that link would be logged in your Free Downloads Log.
The only transaction for you I'm seeing without any attempts logged for some items in the order would be on Jan 3rd for the buyer with initials Y.J., who has not attempted to download her bonus items. She may be getting confused by receiving your common thank-you email for the order as a whole, plus a separate thank-you email for each item in the order, as the item-specific messages only contain a link to the download page for that particular item and not any other items in the order.
To avoid that sort of confusion, you may want to rely on sending just the one, common thank-you email for every order, which will contain a link to the download page for all items in the order, and just disable all your product-based emails. In the settings of each product, tick the box to Enable Templated Email, then leave the Email Message field above that blank, and then click Next until you can Submit changes; this will disable the item-specific emails for that product.
