Please don't mix multiple issues in a single ticket. What is this bug report about?

The build script adds nothing that is not desired. It starts with the list of package we give it and adds Depends/Recommends to ensure all dependencies are fulfilled.

If you want to prove me wrong, then give us at least the configuration directory you used...

Also I don't think that duplicate menu entries are problematic. Sometimes you want some entries at two places. I don't know if it was wanted in this specific case that said.

I used apt-rdepends to see on what those added packages depended and they didn't depend on anything I wanted.

I used the live-build-config git and edited the kali-config/variant-light/package-lists/kali.list.chroot file and added the list of packages I mentioned earlier then build it using ./build.sh --variant light --distribution sana --verbose

I'll let you judge on the duplicate issue but here the example of what I saw: in the 'Wireless' menu, there is Aircrack-ng, then in that same Wireless menu, there is a subdirectory called 'WiFi' and Aircrack-ng was in there too.

So looking at your list, you have mana-toolkit which depends on at least metasploit-framework, sslsplit, dsniff, stunnel4.

For nasm and nmap, they are dependencies of metasploit-framework pulled by mana-toolkit.

For the menu issues, please make a complete list of things that look wrong according to you and file it in a separate ticket. Thank you.
