answer mark in the overview but question is not answered

[JL23]

The overview shows these yellow answered flags

But the question is actually not answered (first in the picture: What does a greengrocer weigh - SAP Answers) but the other question with this flag is answered (How many potatoes fit into an empty sack? - SAP Answers)

Just found out that another moderator (who else could do that?) accepted an answer to this question. But this answer is still in pre-moderation.

Hmm, either it should not be allowed to accept an answer in pre-moderation, or it should not be allowed to accept an answer while there are still answers in pre-moderation, or the item should not be flagged as answered if the answer cannot be shown.
