This is not a problem unless you use very old DOS. You're much more likely to cause more harm than good trying to correct this, especially in the extended partition. And for no good reason!

I there a way to modify the kickstart file so that we don't get this kind of messages .

man sfdisk shows this hopefully useful option:

       -L or --Linux
              Do not complain about things irrelevant for Linux.
