Uname command still shows the old kernel

I installed KernelCare and registered my trial license by switching to Oracle Linux 7.6 because I could not install it on Oracle Linux 6 (U9) due to missing dependency librpm.so.3()(64bit), needed by kernelcare-2.22-1 package. I updated the kernel and rebooted the system and the uname command still shows the old kernel, so a new one was not installed. How to commit the new one?

Hello,

The command ‘ uname ‘ displays the information about the system.
