Multiple Exposures Warning. 114 users (14,82 %) saw multiple variations and were automatically removed from results. Check for bugs in your implementation, event tracking, or data pipeline.My question is: How can GrowthBook determined that my users are seeing two versions of my AB-test ?

10/01/2025, 8:13 AMI don't get how GB is supposed to understand what my users i seeing. What i believed is that growthBook only know what version of my AB is selected by the gaId of the user.
The only way for my user to see another version is by switching gaId, but in this case it create a "new" user in my experiment, thus it shouldn't exlucde no one.
What am i missing ?
