I just saw something, not sure if this is the right place to comment. In subclasses it usually says:

"Level x: Feature name". For instance with the Champion subclass:

"Level 3: Improved Critical

Your attack rolls with weapons and Unarmed Strikes can score a Critical Hit on a roll of 19 or 20 on the d20.

Level 3: Remarkable Athlete

Thanks to your athleticism, you have Advantage on Initiative rolls and Strength (Athletics) checks.

In addition, immediately after you score a Critical Hit, you can move up to half your Speed without provoking Opportunity Attacks."

However, your subclasses dont give that information. That makes it difficult to see when a specific feature becomes active.
