My licenses are all correct. To reiterate: The Minetest media is licensed under various free licenses; relicensing to a "common denominator" is not possible. "Other (free)" is the only correct option here. Palettes can hardly be copyrighted; to further prevent any licensing issues I have additionally shuffled the palettes as the specific arrangement of colors might be protected by copyright to an extent. Also see the reply of the initiator of Lospec regarding this issue, in which he is confirming this.
TL;DR: The license "other / free" is the only viable option; the palettes don't pose an issue.
CDB does not allow publishing of works licensed under "Other (Free/Open)", and probably should continue to disallow it: if a license exists that actually IS Free/Open, then it is worth adding as an explicit option.
The fundamental problem is that CDB currently does not allow publishing of works that have any more complex licensing needs than "one license for code, one for media". Workarounds thus far have centered around licensing the code as a bundle, and media as a bundle, under terms that are compatible with all components, but there was never any guarantee that that solution would continue to work in all cases.
A way to fix this was floated as a discussion topic, and IIRC some attempts at a proof of concept implementation had even been made ... but now I am escalating this to a formal proposal: https://github.com/minetest/contentdb/issues/377
as mentioned on discord, please fix your licenses
