It only shows characters that can be farmed from current events, or that can be awakened from events, as long as they're new. For example, I haven't awakened yet the SR Botamo and Magetta to Bota Magetta, so that feature used to show me those two cards (but not anymore).

You can also tap "How to use" to see how it works.
