No site design tab

As shown in the image it doesn’t show the site design tab like in the tutorials I’ve watched instead it shows the branding and theme tab I don’t know what to do.

What is your Ghost version?

after running “ghost -v” it says:
Ghost-CLI version: 1.19.3
Ghost version: 4.47.3

my site:

Your website source shows Ghost 4.3.

so what should I do? because I can’t update it, it shows me the following error:

:heavy_check_mark: Checking system Node.js version - found v14.18.3

Did you update node? Maybe try ghost buster, and then ghost update—force?

I already tried both options ghost buster and update --force. No, my server only supports node 14.x.
btw, I’m using my shared hosting from Hostingspell and I installed ghost via the cPanel terminal.
