[WriteLog] Wrong Prefix in WPX

[kk9a@arrl.net]

I worked FY5FY/F in the WPX contest.  If I understand the rules correctly
his prefix for multiplier purposes should be F0.  My version of Writelog
(10.31C) shows his prefix as FY5 and the country as French Guiana.  I can
edit manually edit the country prefix to F and this changes the country to
France, however Writelog will not let me edit the multiplier prefix which
remains FY5.  If I log his callsign as FY5FY/F0 Writelog uses the correct
country and prefix, but that's not really what he sent.  I'm not sure if
this problem was fixed in later versions.  Is there a way to work around
this?
