commandnameprefix=sempre não resolve definições conflitantes de \highlight e \comment, algum conselho?

Question

Apesar de ter colocado \usepackage[commandnameprefix=always]{changes} no preâmbulo, ainda recebo erros para:

Erro LaTeX: Comando \comment já definido. Erro LaTeX: Comando \highlight já definido.

Você poderia me dizer o que há de errado com meu preâmbulo abaixo?

Desde já, obrigado!
