Are you missing other AA charges on 10/16 in that screen shot? Normally this can be explained by a difference in how transaction and daily bonus points are summed and rounded.

$5.60 is 6 base points (rounded up) per transaction.

This would make a lot more sense if it was 4 charges of $5.60. ($5.60*4 = $22.40, which rounds down to $22 for the daily merchant 2x "bonus" points for 44 points to spread across 4 transactions, or 11 bonus points each)

In this case it looks like the portal logic missed grouping some of the merchant bonus together with a base 6 point charge, so you should see a 1x charge around that same timeframe.

My impression is that the portal is doing a lot of heavy lifting on generating this points display compared to how the points allocation is actually tracked on the back-end system.
