Laptop keyboard's caps key acting like tab?

Hi, not sure if this is in the right section. I have a Dell XPS 15 and the keyboard that originally came with it has been working fine until recently. I noticed that when I rename a file, and press the caps key, it acts as tab instead. It is very difficult to rename files when caps keeps tabbing out. I've googled the issue and haven't found any fix. Is there anything I can do to solve this problem?
