If I search for +βαπτω in the Greek Bible (LXX + GNT), the hit on I Peter 3:21 is out of order. It appears between Acts and Romans (see first screen shot). The error persists if I remove the parallel ESV pane. It persists if I only search for βαπτισμα.
The order is correct if I search in NA28.
If I search for αντιτυπος, the order is still incorrect when searching the Greek Bible but is correct with NA28.
Things get really interesting if I search for υπομιμνησκω. (See second screen shot.) The order of verses is Luke, John, 2Pet, 3John, Jude, 2Tim, Titus.
I am running Accordance 12.2.9 under MacOS 10.13.5.
