WebStorm put spaces instead of tabs

I have setup WebStorm to use tabs under Preferences -> Editor -> Code Style -> Javascript. I have checked "Use tab character". I have not checked "Smart tabs".

When I make a tab character in any javascript editor I get two spaces.

Why does this happen?

I have a different project on the same computer on which this problem is not present.

I'm running on Mac Book Pro and WebStorm 2017.2.3.
