Why was it renamed to Albatross18 in the US?

I have always wondered why it they have chosen to change its name when they opened the US server? Was it because the name was already patented there, or because the name wasn’t easily pronounceable for English speakers? Although in the EU it has kept the original name.
Btw I have read a couple of posts of old players who know this game only by this name, they probably never knew it was known as Pangya elsewhere.

I honestly don’t know, maybe it was a very strange word for English speakers but the word is not difficult to pronounce. It’s very strange why they chose the name albatross18 because the word albatross is something only people who play golf know.
