已经出境为啥网上I-94还在呢？

我是今年B2签证飞机往返的美国，所以只有电子的I-94，查询网站上说“A traveler will have access to their most recent admission record on the I-94 website until departure from the United States. An admission record will no longer be available to the traveler on the website once he or she departs the United States.” 上星期已经回来了，但是在网站上还是能查到自己的I-94，哪位大侠知道这是怎么回事？应该找谁呢？不会算我逾期滞留吧，这就太坑了。
