Unable to add years for Zambia notes [resuelto]

P# 37b and P# 38b on the following 2 pages should be listed with the year 1992, per the note year, but instead have a question mark, which I am unable to change as it grayed out . Can someone assist in correcting the years on these please?

N#204046

N#203874

Thanks,

Tony

Done, thanks! =)
