I don’t know if that’s the same kind of issue, but I’ve found for revenue tickets, and particularly the app, the boxes with the lowest fare are often off from the actual lowest fare I can find. Perhaps somehow those boxes at the top are using older cached data or something. Like I said, this has been a problem for a long time, more so on the app. Pretty sure I have seen this for awards as well.

I recently saw a new version of this, as typically the box at the top will show a lower fare than I can actually find - and the lowest fare - even after bringing up show more, scrolling through the options, then trying to sort, is not there. A few days ago, when sorting, it showed up some fares that were lower than the lowest showing on the box at the top. I’m not sure if it was displaying the lowest option it had before the search was 100% complete, and then lower options appeared after, or some other reason, but that’s what I’ve noticed. .
