Can someone tell me how to fix this?
No, not without any information.
This is a issue with your Google setup, and I believe it is easier for you to get help on a google forum. The events in Construct is not that hard.
If you want help, try to provide a full description of your events and the setup for your app in google console, and your game in Google Play.
Then possible someone can help out.
Also post stuff like this in the How do i section.
