Help understanding the double events to Mixpanel

Hi,

When I go to Integrations > Mixpanel > scroll down to Integration Events, it looks like there are 2 simultaneous events each time, with different but related payloads. Can someone explain what’s going on? I’m not a dev (anymore :) so it might be obvious. I’ll paste the payloads below in case it’s helpful.

Thanks,
TOM
