Kickstart and Boot Loader Problem

Hi,
I have created an ISO for Kicktart installation, everything is working without problem except boot menu creation.
GRUB has been configured with wrong Kernel for default. Actually "4.1.12-37.4.1.el6uek.x86_64.debug" has been configured as default kernel.
Is there any way to controling boot loader creation during Kickstart installation and force it to choose right kernel as default.
This issue is not happened after manual installation.
