My Saviour and your savior is not the same"

At a young age, I started reading the King James version of the bible. I noticed the word Saviour was used through out the bible, many ,many times. I think the word Saviour spelled with a U was done for a reason. The word Saviour is a title for our true and macnificent God. Now, if this is the case, Why are so many spiritual and religious book written with the savior without using the U. I think using savior instead of Saviour Is making it whole different meaning. I can be reading such a great
spiritual or religious book that might be up lifting to me until I come to the word savior and right away, it takes from the true meaning of the book that I'm reading. I think authors that write spiritual or religous books should refram from using savior because it feels like they're are taking away from The identity of God. This only my opinion, but it makes a difference to me.
