I understand your confusion.. There is a simple answer for this issue.
First you fixed it. Then most likely you requested indexing by google bot.
Well the glitch in this is your page has been crawled, but that is all you know. What you and everyone else, including me, doesn't know is when that crawled data will be included in Google's Index.
Till then, Google will use the data in the index.
This process could take 1 day to I don't know when.. but generally less than a couple of months.
