Singlife Comprehensive Critical Illness vs DIRECT - GREAT CRITICAL CARE

So, here's the thing I've been looking out for critical illness coverage.

​

Question:

1. Singlife Comprehensive Critical Illness covers 132 conditions is that also covered in the GE CI rider where it stated 30 critical illnesses (see screenshot)?
2. If I were to get GREAT Critical Cover: Top 3 CIs does that means it doesn't cover those 30 critical illnesses? I little confused about what is exactly covered
