Thank you for your feedback. But its not just that, it is everything. It is a recurring theme. There has been a nine-point turn around, an eight, a seven, a six and a five, but never a 12. Structurally, it does not convince.
A twelve is clearly mentioned in the text.
( z0 mention :ARG0 ( z1 text ) :ARG1 ( z2 person :mod ( z3 temporal-quantity :quant 12 ) ) :ARG1-of ( z4 clear ) )
(z0 / mention-01
    :ARG0 (z1 / text)
    :ARG1 (z2 / person
              :mod (z3 / temporal-quantity
                       :quant 12))
    :ARG1-of (z4 / clear-06))
