Problems downloading Beatles

When trying to download The Beatles double pack I get the following message when I try to import folder.
“Error while parsing song content:
SongFileModel::readFromBuffer-WARNING-A part of the file was not used by
parser. The unused size is 4304
File contains more data than expected”
Can someone please tell me what I am doing wrong?

Just completed downloading the new software and successfully downloaded
the Beatles pack.
Thanks a million for your help.
