Conda build is stuck with some unrelated build aterfacts. Unable to purge them.

What happened?

I try to add a dual license to a recipe with this entry:

about:
  license:
    - Artistic-1.0-Perl
    - GPL-1.0-or-later

At build time, I get an error conda.auxlib.exceptions.ValidationError: Invalid value ['Artistic-1.0-Perl', 'GPL-1.0-or-later'] for license

Since, when I try to build any recipe. I get this error, even if the meta.yaml don't contain those licenses. For example, this file (with an empty build.sh next to it) produces the above error:

package:
  name: test

I was able to solve the issue by using conda build purge-all, but this behavior is clearly a bug.
