In order to simply the names of the fields from our Meta Ads connector we removed the prefix "adInsight_" from its columns.

For example, instead of: "adInsight_clicks"

Now you'll see: "clicks" which is much cleaner and nicer!

Here's what you need to do:

1. Open your Looker Studio dashboard
2. Click on the chart that is broken
3. Edit the data source (it's the pencil on the data source you can find under Set-Up > Data Source
4. Then click on "Refresh Fields" on the lower left
5. Confirm the changes and you're done!

We also have a video tutorial on this page: here.
