Cannot display initialkey

When I analyze with MIK, i select in preferences "Update initial Key", but in MP3Tag, in the initialkey column, no thing appears, but in Traktor 1.2.3 i can see the values in the key column.

Why i can't see the values in mp3tag???

Thanks

Did you have a look in the extended tag-view of MP3Tag (Press ALT+t) whether there is a field listed with the information you are looking for?
If yes, waht is the name of the field?

It may be due to your settings which tag versions you read and which are in the files.
See which tag versions are in the files (APE, ID3V2, ID3V1) and see which ones you read with MP3tag, see File>Options>Tags>Mpeg
