On my site the MailChimp status data - that shows the number of products and orders synched - shows that the number of orders synced to MailChimp is greater than the number of possible orders:

I attempted re-syncing the connection to see if it would clear up, but it remained at the same count afterwards.

Could you please check what MailChimp plugin reports in wp-admin MailChimp plugin panel?

Same there 馃槮 - so likely a bug in their plugin as well.
I suppose we could add a simple check in the calypso logic that prevents the synced order number from being larger than the total order number.
I would not want to do that. I want Calypso to be 100% compatible with the plugin. All the fixes need to be done on plugin side.
Since this bug is in the plugin, do we have a contact there we can pass along this issue to @budzanowski?
Looking through the maintenance queue and wanted to bump this. @budzanowski ^^
I'm not 100% sure that there is an issue with the plugin though or that we need to contact anyone?
I think we just have the numbers reversed in the Calypso interface. Your Nov 7th wp-admin screenshot shows "103 out of 104" (where calypso shows 104/103) and mine shows:

Ha I didn't notice that the first time - indeed it does look like we have the numbers reversed! Good catch @justinshreve
