[CQ-Contest] CQWW/KL7 in lower states

[Frank Grossmann]

Hi all,
hi contest committee , Randy,

sorry if this has been asked before.

I worked KL7HM who is in Arizona, zone 3.
He was sending out "KL7HM" as callsign, and Win-Test recorded this as Alaska, with a probable mistake on the zone side.

Am I allowed to put him in the log as KL7HM/K7? 
Or would that eliminate the validity of the QSO or make it unique?

Thanks
Frank
