Token symbol doesn't change on adding properties on chain

Question

I was able to add some properties in substrate-node-template chain_spec.rs file. But instead of XCAV token symbol it gives MXCAV. Is this issue or I am doing something wrong. Any advice or reference link would help a lot. And also try to add total_supply with properties but doesn't work.

pub fn local_testnet_config() -> Result<ChainSpec, String> {
    let wasm_binary = WASM_BINARY.ok_or_else(|| "Development wasm not available".to_string())?;

    let mut properties = Properties::new();
    properties.insert("tokenSymbol".into(), "XCAV".into());
    properties.insert("tokenDecimals".into(), 12.into());
    properties.insert("ss58Format".into(), 42.into());

    Ok(ChainSpec::from_genesis(
        // Name
        "Local Testnet",
        // ID
        "local_testnet",
        ChainType::Local,
        move || {
            testnet_genesis(
                wasm_binary,
                // Initial PoA authorities
                vec![authority_keys_from_seed("Alice"), authority_keys_from_seed("Bob")],
                // Sudo account
                get_account_id_from_seed::<sr25519::Public>("Alice"),
                // Pre-funded accounts
                vec![
                    get_account_id_from_seed::<sr25519::Public>("Alice"),
                    get_account_id_from_seed::<sr25519::Public>("Bob"),
                    get_account_id_from_seed::<sr25519::Public>("Charlie"),
                    get_account_id_from_seed::<sr25519::Public>("Dave"),
                    get_account_id_from_seed::<sr25519::Public>("Eve"),
                    get_account_id_from_seed::<sr25519::Public>("Ferdie"),
                    get_account_id_from_seed::<sr25519::Public>("Alice//stash"),
                    get_account_id_from_seed::<sr25519::Public>("Bob//stash"),
                    get_account_id_from_seed::<sr25519::Public>("Charlie//stash"),
                    get_account_id_from_seed::<sr25519::Public>("Dave//stash"),
                    get_account_id_from_seed::<sr25519::Public>("Eve//stash"),
                    get_account_id_from_seed::<sr25519::Public>("Ferdie//stash"),
                ],
                true,
            )
        },
        // Bootnodes
        vec![],
        // Telemetry
        None,
        // Protocol ID
        None,
        // Properties
        None,
        Some(properties),
        // Extensions
        None,
    ))

Well... This question is pretty simple. (you might find it's a little bit stupid later, LOL)

M is the unit. M for million.

You can mint more tokens to that account. And you will see BXCAV, which is billion. Cheers!
