Kernel version problem in installing packages

Hello, when I try to install a package (like mwan3) and click on "install," in the bottom of the floating window, I receive the following error in Details:

The installed version of the kernel package is not compatible, it requires 5.15.147-1-13427c9c... while 5.15.145-1-a189338a... is installed.

My device: Xiaomi AX3000T
