Duplicate Events Issue

Hi everyone, just wanted to ask about an issue I’m facing while waking for Make support to get back to me on this. I’ve been having a problem where there are duplicate events occurring - you can see below.

Upon checking Square developer dashboard, there are no duplicates on Square’s side (attached screenshot of relevant event).
Square support has also informed me there are no duplicates or issues on their end.
The issue only happens when there is roughly a 4 second difference between the triggered at & sent at timestamps. Any ideas on what might be causing this?

Thank you!
