CFA sections name vs. group for L3

As I am about to start studying for L3, I noticed that unlike L1 and L2, CFAI did not explicitly name chapters such as fixed income, equity investments, etc. Can you tell me to which group these chapters belong to? Ethics, Derivatives and AI are all very self explicatory.

Book 1 - Ethics and Behavioral Finance Book 2 - Private Wealth Management and Institutional Investors Book 3 - Economic Analysis, Asset Allocation and Fixed-Income Portfolio Management Book 4 - Equity Portfolio Management, Alternative Investments, Risk Management and Derivatives Book 5 - Trading, Monitoring and Rebalancing; Performance Evaluation, and Global Investments Performance Standards

Thanks.
