Is this a Pokemon Sun/Moon translation mistake?

I doubt it too. The only reason I can think of for this is that they just assumed that there was the same number of UB2 and UB4. Also weird is the fact that the two celesteeles I caught I did so in the desert, while nothing has appeared on the park. If there are two places, shouldn't there be one in one place and one in another?

I actually found both in the park myself since I had no idea where the desert was at the time. Have no clue what determines how to find them.

Have you been able to find any Celesteeles on the desert, then?
