Bug: "Allow later license versions" is not honored

Whenever I submit art after unchecking the "Allow later license versions" checkbox, the submission nevertheless states "The authors of this content agree to license it under later versions of the licenses they selected above.". That statement only goes away after another edit.

I also notice that many entries in the LPC art collection seem to allow later versions, even ones which are obviously based on the LPC base assets. And the file COPYING from the LPC base assets did not allow later versions for art. Hence I assume that those flags were also set unvoluntarily.
