Imo caucasus and wca components are interchangeable for Euros. Sometimes some of them might score 5% caucasus and 5% wca while the others might score 10% caucasus and no wca. These 2 french results are a proof of that and this type of thing isn't any different from how some west asians might score for example 5% north euro and 0% western euro while the others might score 0% north euro and 5% west euro
