I was told by FB Support that my purchase event was being fired at a wrong stage. I then used event setup tool to delete the event and set up a new purchase event in its place. However, upon verifying with fb pixel helper later, it showed me 2 purchase events being fired, one of which was manually set up, as shown in the screenshot.
Can someone please tell me what to do about this? Its bugging me and there has been a significant drop in my conversions as well. Would appreciate any kind of help that i can get.
