When in the Bing Ads web-interface within the main "Campaigns" tab... there is a right-side column (gray background) that lists all available campaigns in the account, and each campaign can expand open to show the ad groups within.

If you click on one of the ad groups listed in the left-side bar column, and then try to view it's Keywords or Ads on the right (the data tables), the data that populates in the tables is NOT specific to the ad group you clicked on, but rather is an aggregate of all campaigns!

This never used to work like this before, and is contradictory to the functioning within the Adwords Interface.

I consider this a bug, that must have occurred in a recent update, since the functionality has changed dramatically, and is causing much frustration for me and the others in my office.

Please correct this issue. That is our suggestion.
