Rust Version

rustc 1.71.1 (eb26296b5 2023-08-03)

Clap Version

4.3.21

Minimal reproducible code

use clap::{Command};
fn main() {
    let mut app = clap::Command::new("clap-bug")
        .multicall(true)
        .version(env!("CARGO_PKG_VERSION"))
        .propagate_version(true)
        .subcommand(
            Command::new("clap-bug")
                .author("Author Here")
                .about("Program name")
                .arg_required_else_help(true)
                .subcommands([Command::new("list").about("list applets")])
                .subcommand_value_name("APPLET")
                .subcommand_help_heading("APPLETS")
        );

    // Parse args
    app.get_matches_mut();
}

Steps to reproduce the bug with the above code

cargo run -- -h

Actual Behaviour

author and program version are missing in the output:

Program name

Usage: clap-bug [APPLET]

APPLETS:
  list  list applets
  help  Print this message or the help of the given subcommand(s)

Options:
  -h, --help     Print help
  -V, --version  Print version

Expected Behaviour

This is the behaviour with clap 3.2.25:

clap-bug 0.1.0
Author Here
Program name

USAGE:
    clap-bug [APPLET]

OPTIONS:
    -h, --help       Print help information
    -V, --version    Print version information

APPLETS:
    help    Print this message or the help of the given subcommand(s)
    list    list applets

Additional Context

I also tried to put the author and program name in the main Command, but this does not change anything.

This is expected behavior for all programs. This was changed in 4.0.0 (see also #4132).

See help_template for restoring the old behavior

Oops, sorry. Thanks for the quick reply.
