Latin is a little funky in that a language will definitely change over the course of hundreds of years.
In the Classical pronunciation (which is most common in the US), v is pronounced as a w.
In the Ecclesiastical pronunciation (which is most taught in Europe), v is pronounced as a v.
The letters "v", "u", and "w" all originate from the various sounds the letter has taken over time. In ancient times, there was just V and it had to make do with multiple sounds until the extra letters were added to make it a little easier.
Also correct, and it's been added, but unfortunately it takes a while for our changes to go live for users.
