Cigler Conjecture 7.5 printed second-line refutation

Refutes only the printed second line of equation 7.11, Conjecture 7.5 in arXiv:1801.05608v3, at k = n = 1; literature-attested, new_counterexample_claimed = false. No claim that the intended proposition is false or its proof has a gap; no verdict on the first line or Conjecture 7.6 (the reported 7.6 counterexample was a transcription error). No priority is claimed for the determinant values or identification of the printing error.
