Ah, sounds like a misunderstanding.

To determine what rewards you should expect, first look at the "tier" of the defense mission you're running. The majority of them start at tier 3 now, including Helene. After that, look at the respective drop table, i.e. Tier 3. So Tower III Mobile Defense Key is right.
