Super Bomberman R: 142445 is "EUR" but is the one sold in [CH]. The general English EU release is the UXP. The UXP version is the only one that can be without a TLD. I just fixed the UXP version, which was in the DB erroneously as [UK].
For Owlboy, initially it was rejected because of removing [FR] from a listing with the red notice text. That was the quick reason. After checking now, it seems this particular one is in-fact a general EU release, sold in UK and France but also Italy and other countries.
EU entries are a mess, besides the franken-entries we know about. Some EU collectors will go and put TLD to reflect languages, or will uneedingly put [UK] on English releases when there is no non-UK English version.
