About the application period of the Limitless Annual Pass

I saw an event ad for the Limitless Annual Pass and purchased a 1-year pass.
After purchasing the Limitless Annual Pass and applying the code, I noticed that the Limitless period was extended by 365 days. According to the sales page, the Limitless Annual Pass provides 1 month in addition to 365 days, and now shouldn't it provide a total of 2 months because of the event?
My Limitless period is still only extended by 365 days.
