How to apply for Global Talent Child visa (outside UK)

I am applying the Global Talent Child visa for my 4-year old son (apply together with me).

  • At the ““Declaration”” page, I chose:
    “I am the parent or legal guardian of the applicant who is aged under 18 and completing and submitting the form on their behalf”

  • Then the next page entitled “Third Party Declaration” asks “In what capacity are you representing the applicant(s)” where I chose “Family Member”. Then it asks me "How are you related to “my name” (which is myself)? So it is asking how I am related to myself. Am I making any mistake here as I already provided all my details earlier?
