STEPS TO REPRODUCE

- hosts: localhost

  vars:

    t: [k0, k1]

    l1:
      - {k0: A, k1: B, k2: [1], k3: foo}
      - {k0: A, k1: B, k2: [2], k3: bar}
    r1: "{{ l1 | ansible.utils.keep_keys(target=t) }}"

    l2:
      - {k0: A, k1: B, k2: C, k3: foo}
      - {k0: A, k1: B, k2: C, k3: bar}
    r2: "{{ l2 | ansible.utils.keep_keys(target=t) }}"

  tasks:

    - debug:
        var: r1
    - debug:
        var: r2

gives (abridged)

  r1:
  - k0: A
    k1: B
    k2:
    - 1
  - k0: A
    k1: B
    k2:
    - 2

  r2:
  - k0: A
    k1: B
  - k0: A
    k1: B

EXPECTED RESULTS

  - k0: A
    k1: B
  - k0: A
    k1: B

  - k0: A
    k1: B
    k2:
    - 1
