Hi Luke!
Thanks for getting in touch with us. Let me try to help you with this topic.
I made a few tests importing events from Facebook but could not reproduce the duplicate images. You mention that these are coming from recurring events from Facebook, so this could be happening when dealing with recurring events.
When getting duplicate images for an import, do all the event images for that import get duplicated or just some?
Could you please share a Facebook URL from where you are experiencing the duplicate images? We’ll try to reproduce the issue on our side.
Thanks,
Victor
