Ok, I found the dependency why it sometimes works and sometimes
doesn't. It's about the point position when changes affect files in
different directories. If the point is located in a different place than
the line where the files are, for example, a line that points to a
directory - then marking all files with the <M> key doesn't include all
files.

Unlike, the <U> key, which unmark all files regardless of position.

Rather, it has nothing to do with the repository itself or the backend.
