I'm confused about how long Romance Rewards are good.

I asked a question on the site because our past 2 trips were not showing up in our activity. I was told: The Romance Rewards Program is only retroactive up to 13 months.

However, the Couples website says:
Nights Stayed are cumulative. No benefits are earned on complimentary stays or Industry Discounted Rates. Nights expire 4 years after they are earned.

Does anybody know which it is? I sent an email back asking about this but have not received a reply.
