## Issue **Loop Metadata variables are changing** In the [For each loop](https://cloud.google.com/application-integration/docs/configure-for-each-loop-task) and [While loop](https://cloud.google.com/application-integration/docs/configure-while-loop-task) tasks, there's a `Loop metadata` variable in which you will find duplicate keys for the output variable–for example, `Current Iteration Count` and `current_iteration_count`. We recommend you to use the variables that contain the underscore (`_`) symbol because the other keys are being deprecated. For more information, see [Known issue: Duplicate keys in the Loop metadata](https://cloud.google.com/application-integration/docs/known-issue#duplicate%5Fkeys%5Fin%5Fthe%5Floop%5Fmetadata).
