It’s highly probable that the issue is occurring due to the unnecessary creation of a custom event in the GA4 configuration. The GA4 interface allows for the creation of ‘new events from existing events’, a feature that might inadvertently result in duplicated event fires when incorrectly configured. You might want to check if you’ve actually configured such a custom event which could be causing multiple triggers. This may explain why the ‘view_faq’ event triggers multiple times for a single button click.
