Post Click vs. Pose View Conversion Reporting

We have been using the backstage API for a while, and have been able to extract segmentation of conversion according to post click and post view attribution. These metrics came through the following values in the API response:
cpa_actions_num_from_clicks
cpa_actions_num_from_views

Recently, the API response has not provided these values, and we only see cpa_actions_num when it comes to conversions. Checking the platform's UI, it appears the change is reflected there as well. The documentation still references these metrics.

Has there been a change in the platform itself or is this a temporary issue?

Thanks
