Considering you have not enabled the License Checklist on a submission for whatever reasons, it still gets generated with default permissions on the License section of the submission.
Now, this is not much of an issue considering if you are fine with having it, but in some cases, like mine for example, where I use my own license and don't want to have the checklist enabled, this is actually weird and confusing for the people to see two different licenses stated at the same time (checklist and your own one) regardless of the license statements.
Here's an example of what I mean.
The idea is simple, if you choose to not enable the checklist, it simply should not get generated either.
Generally speaking, if the author has defined their own license, there is no need to generate an automated/default one along with it.
