Google announced that on September 21, 2016 they will be retiring the "converted clicks" metrics and replacing it with the "conversion" metrics.
Google said this is "in order to simplify conversion measurement" calling converted clicks "a limited way to measure the results from your ads because it is tied to a single click and it's doesn't lend itself to measuring behavior that spans multiple conversion events or multiple clicks."
Google added if you are using "Conversions" for reporting and bidding, no action is required.
If you use Target CPA or Enhanced CPC and your primary bid metric is set to "Converted clicks" at the present time, you should plan to update to "Conversions" by September 21st.

In settings you can adjust the conversion actions in AdWords.
