Hello Bradley!
Thanks for getting in touch with us! Let me help you with that.
Unfortunately, Event Aggregator does not support importing recurring events at the moment. So, the behaviour you are experiencing is the default behaviour for those kind of events.
I wasn’t really aware that Facebook had recurring events as an option. This could be a new thing from their side. If you think this should be added as a feature to Event Aggregator, you could share with us that idea in our User Voice here > https://tribe.uservoice.com/
If you need help elaborating this a bit more, just let me know and I’d be happy to help.
Best,
Victor
