Fomo defaults to show your last 30 days' of online purchases.

If you have orders outside that range, you'll need to increase the Order Threshold in the 'Design & Settings' tab within your BigCommerce account.

This will trigger a new order import and you'll see your newly scoped Fomo notifications in your Events tab within your Fomo account. If you still don't see your orders in the 'Remove Orders' tab, let us know.
