JSLint ignoring tab width

I'm editing some Javascript in PyCharm and having trouble with JSLint. In particular, it keeps saying "Expected 'whatever' at column 9, not column 5". This is because my tab width is 4, not 8. But the options page for JSLint DOES have the tab width set at 4 also - it's just ignoring this when inspecting my code.

I will probably just disable JSLint because it is not customizable enough for my coding style, but the tab thing seems like a bug rather than a feature.
