Storage calculations errors?

Settings > Storage

I get an accurate 30Gb used out of 128Gb total, but below that I am told that there are the following:
Documents and other: 121Gb
Audio: 87Gb
Images: 9.9Gb
System: 1.1Gb
etc.

Is this normal? Even my arithmetic knows these numbers are nonsense!

Thanks.
