Research Papers / Registration of a paper in an identified academic field? [2]

Hello, I am currently reworking a paper as the reviewers asked for Major revisions (which is what I expected).

One of the remarks is the registration of the work in an identified academic field.

However, when I read several academic journals and publications, I see that many papers are interdisciplinary: for example, a journal rather focused on sociology welcomes articles from researchers in the communication, media or design section. Or the other way around.

Is it mandatory to register in a single academic field through a paper? It seems quite restrictive to me.

Thank you for your opinions.
