-unversioned issues

Why does the -unversioned command always appear when I package?

Because my requirement is to load the pak file of project B on project A. If I use this command, “Package was saved unversioned and the current process does not support loading unversioned packages” will always appear when loading.

I’d like to remove the “-unversioned” command when packaging, How can I solve it?
