KernelCare on Oracle Linux 6 and 7

Hello,
today I've tried to install KernelCare on Oracle Linux 6 (U9) unsuccessfully due to missing dependency librpm.so.3()(64bit) needed by kernelcare-2.22-1 package.

I switched to Oracle Linux 7.6 and installed KernelCare and registered my trial licence.
I updated the kernel:

[root@oel7 ~]# uname -a
Linux oel7.localdomain 4.14.35-1818.3.3.el7uek.x86_64 #2 SMP Mon Sep 24 14:45:01 PDT 2018 x86_64 x86_64 x86_64 GNU/Linux
[root@oel7 ~]# /usr/bin/kcarectl --update
Updates already downloaded
Patch level 1 applied. Effective kernel version 4.14.35-1902.4.8.el7uek
Updates already downloaded
Kernel is safe
[root@oel7 ~]# /usr/bin/kcarectl --uname
4.14.35-1902.4.8.el7uek

Reboot the system and then:

[root@oel7 ~]# uname -a
Linux oel7.localdomain 4.14.35-1818.3.3.el7uek.x86_64 #2 SMP Mon Sep 24 14:45:01 PDT 2018 x86_64 x86_64 x86_64 GNU/Linux
[root@oel7 ~]# /usr/bin/kcarectl --uname
4.14.35-1902.4.8.el7uek

The uname command still reports the old kernel.

No new kernel is installed.

How can I commit the new kernel?
