Numbering of steps is incorrect

If cargo +nightly contract build is executed, the step [4/5] appears two times in the output:

$ cargo +nightly contract build 
 [1/5] Checking ink! linting rules
Checking with toolchain `nightly-2022-03-14-x86_64-unknown-linux-gnu`
    Finished dev [unoptimized + debuginfo] target(s) in 0.10s
 [2/5] Building cargo project
    Updating crates.io index
    Finished release [optimized] target(s) in 1.45s
 [3/5] Post processing wasm file
 [4/5] Optimizing wasm file
 [4/5] Generating metadata
    Updating crates.io index
   Compiling metadata-gen v0.1.0 (/tmp/cargo-contract_VjAOjf/.ink/metadata_gen)
    Finished release [optimized] target(s) in 2.08s
     Running `target/ink/release/metadata-gen ''`
 [5/5] Generating bundle

It could just be a simple fix of using six steps instead, but I have a distant memory that the number of steps is dependent on the CLI flags used.
