Conversion tracking is one of the key metrics many advertisers use when determining if they will run a PPC ad and how much they are willing to spend on an ad. So when it goes missing, advertisers become really concerned.
A Google Groups thread has confirmed reports that for some Google AdWords advertisers, the screen that displays conversion tracking, is not displaying the data as it normally does. Don't worry, the data is not lost, it is just not visible in that current location, at this present time.
To see your conversion data, you must click on the "Customize Columns" link in your data table and show your relevant conversion columns. You should then see the conversion data. Keep in mind that you have to do this every time because these columns will not stay visible if you refresh the page or navigate to a different part of your account.
Google's AdWordsPro.Jordan said the team is aware of this bug and is working to address it. For the time being, you need to use the method above to get to your conversion data, each and every time.
For now, I’d suggest using the manual workaround I just described or using your reports to determine your conversion performance for now. Sorry for the trouble.
