No, look at your message carefully I says the earliest points expiring are expiring way past 18 months, in 2027.

So that's presumably why your message changed.

Or do you actually have any points expiring in 18 months that it didn't show?

Because that's the exact same message that I got that I mentioned a few posts above, just didn't provide a picture of. AFAIK, it only appears for those who have no 18 months expirations pending, only 4-year expirations pending.
