I think Petelgeuse's name was originated off of the red star Betelgeuse witch is probably why everyone thinks his name is Betelgeuse and I think that when the manga crossed over to the anime his name changed from Petelgeuse to Betelgeuse. I might be wrong about that though.

An example of this theory:

Manga: "Ahh, I see. It occurs to me that I have been rude. I have yet to introduce myself, yes? I am Petelgeuse Romanee-Conti of the Witch's Cult, Bishop of the Deadly Sins! Entrusted with the duties of Sloth!"

​​​​​Anime: "In the Witch's Cult I am a Sin Archbishop, representing Sloth; Betelgeuse Romanee-Conti."
