When files with a size of 0 bytes are added to the queue, that then change their size before the transfer starts, FileZilla doesn't get the - now changed - file size and thus shows no download progress bar and remaining download time for those files.
To fix this, I suggest to add a file size check before the actual download of a queued file starts.

This is unlikely to ever change for performance reasons.
