Why when I create a new path or layer in Illustrator CC it goes to the bottom of my layers list? Where can I set it up to create them at the top of the list as it usually does?

I don't know if i did something wrong and i didn't notice it....but i was working normally on Illustrator, and suddenly all the new layer i created when to the bottom of the compound of layers i had. It had never happened to me before and i don't know what to do to reset it. It is really annoying.

I really appreciate if somebody can help me!

Thank you!
