As tabelas são cortadas e o cabeçalho do apêndice está em uma página diferente

Question

Como pode ser visto ali a segunda tabela do apêndice está cortada. Além disso, o cabeçalho do Apêndice está na página anterior. Aqui está o resultado:

Answer 1

Bem, o principal problema aqui é que você está usando um ambiente tableque faz sua mesa flutuar.

Por favor, veja o seguinte MWE onde comentei o ambiente tablepara a primeira tabela. Veja também que apaguei vários pacotes não relacionados a esse problema e apaguei comandos duplos usados... Veja que adicionei opção showframeao pacote geometrypara visualizar a área de digitação e margens utilizadas...
