I am working on the main branch updating some files but not the ones on the list below, however whenever I run git status I get the message below with the files highlighted in red which suggests there might be an issue somewhere, I would be happy if someone can please explain what is going on and what I can do to resolve the issue/these messages. It continues to come up.
