As posted in the previous example, usually a TLD would be rejected (besides it being wrong) is if there is only 1 entry in the category for that game. I do not know if the new entry you made was present at the time the edit appeared in the queue, it could be possible that was why it was rejected. It is fixed now.
I do know that EU sections are not complete with all of the versions, and in leiu of creating the missing UK versions, you can put into description the release country of the TLD-less/non UK version. So that it is know that it should have a TLD when the UK version is added, and when that time comes then the release country in description can be removed and the TLD added.
