Certain names autocorrect to ALL CAPS

If I were to right my name like a normal person, it autocorrects to NOAH. Some apps I can change it back, which is very annoying, but on others it doesn’t show the suggestions bar. I do not want to turn of auto-caps due to I am a lazy person when it comes to typing. Also it looks unprofessional when my first name is all caps and my last name looks normal. Why does it do this? How can we fix it, also? Plz
