AdWords Can Increase Bids Higher Than Your Manual Cost Per Click Setting

In Settings > Bidding, you properly selected Manual CPC. However, AdWords just changed this to "Help increase conversions with Enhanced CPC" if you use Conversion Tracking. Click on down arrow, to unselect this "Enhanced CPC" setting, which dramatically increases your costs and distorts the Ad Group Bids that we need to control bid costs. See GamePlan Settings & Tune Bids pages.
