Core file warnings on "licens-sv_SE.txt"

I’m using Shield on a lot of my sites. A problem that has been going on for a few weeks now is that I every day get a warning mail like the one below.

Error message:
The MD5 Checksum Hashes for following core files do not match the official www.ads-software.com Checksum Hashes:
– licens-sv_SE.txt ( Repair file now / www.ads-software.com source file )

This file doesn’t exist in “www.ads-software.com source file” and even if I managed to find a copy of this the core file scanner still warns me.

Can you give me some tip on how to deal with this?
