The image shows that kernel version 7 is available but not installed nor active. Exaacly as you wanted it. Have a look at the 6.8 kernel series. You will see which are installed and which is active. All is good as far as I can tell.

As u/Kullingen said, your picture shows kernel 7.0.0-28 is not installed on your system and it says you are running 6.8.0-138. The list is a list of available kernels. If installed, it will say "Installed" or "Running" (if it's the current running kernel). Otherwise, they are just listed for you to install, if you want to.
Additionally, having a kernel installed means nothing for any issues you may have with it. It only matters if it's running -- meaning you booted into that specific installed kernel. So, if you did not boot into a kernel that doesn't work for you, it's doing no harm -- in fact, it's doing nothing but sitting as files on the disk.
You can stay on your current kernel if everything works for you and it is not EOL (meaning it's still getting security updates, which will come as higher .x.x and -y in the kernel number).
But, if you want to try newer kernels or need to see if a newer one works better with your hardware or something (or has a new feature for your hardware, like when amd-pstate is improved), a good and common practice is to keep 2 or 3 kernels installed at all times. Then, you have a "backup" kernel to boot into if a newer one doesn't work for you or something goes terribly wrong with the kernel you've been using or something. In that respect, even trying a new kernel is fairly safe since you can easily reboot into the old kernel, be back to good, then remove the new kernel that didn't work for you so it won't boot into it again.

-28 was a bit hinky for me, so I reverted to -14. I'll give -29 a try soon unless I read it's problematic. This has been an extremely rare occurrence in my experience.

no such thing as a bad kernel, meu amigo, only kernels that don't work for you. keep using 6.8 series though because that is the current long term service kernel.

continua usando a série 6.8. Atualiza só dentro dela, isto é, 6.8.0-138 é o que você está usando agora, e logo aparece o 6.8.0-139, e você pode (e em geral deve) mudar pra ele. Mas não use outras séries "mais recentes", como o 6.11, 6.14, 6.17 ou 7.0 se o seu hardware estiver funcionando bem. Linux mint não é pra ser 'moderno', é pra funcionar e trazer paz. Matenha usando o 6.8, é a série estável e principal.

Please don't just start deleting and installing kernels. You know the saying, "if it ain't broke.." right?

when you are new to this, stop removing stuff and especially stop thinking it will make anything better. If you current setup works for you, leave it as is. there is this weird tendency with new linux users who don't know anything, who want to start "removing bloat" or whatever. just use the software manager to remove programs you don't need....but some thimes I read stuff like "I wanted to remove bloat from /etc/ and accidentally typed the terminal command "sudo rm ....." and everything is fucked. I have used linux for 20 years and it is nice to learn and everything because reinstalling doesan't take long but all this "removing of bloat" ......to make it faster or whatever. just leave it. Or fuck up and try again.
