I suspect what you may have stumbled across is not that Wally World is suddenly taking OVs (though anything is possible), rather I suspect you have found a loophole where possibly some OVs slip past the current system. If I were you I'd take a close look at those cards which were accepted and those that weren't and see if you can figure out what the pattern is.
