Is this normal?

This is what's called a 'split scute.' You may have just noticed it for the first time, but your tortoise has had this its entire life. Split, or extra scutes happen during development and have been tied to higher incubation temperatures but could also be genetic. It's just cosmetic; nothing to worry about.

Yes I believe some are born like that
