Does web based updates replace rebuilding the container?

I don’t know if I’m doing something wrong, but I tried to do a rebuild via terminal and I’m getting this:

error: Your local changes to the following files would be overwritten by merge:
        templates/import/mbox.template.yml
        templates/web.ssl.template.yml

But I don’t use those templates, and I do not interact with templates files. I delete them and can proceed, but any idea why this could be happening?

And I’m not sure if you were being sarcastic, I have no reason to lie or anything…
