Fill section `^`

[Davincible]

I'm experiencing a stange problem with the fill section. I'm not sure if its related to this plugin or not, but since it's a statusline issue I'm asking here.

Sometimes, not always my statusline likes to fill itself with ^ instead of a space:

The filler used is %=.

Any clue why it might be doing that occasionally ?

this happens when the highlight groups StatusLine and StatusLineNC are equal.

from :h hl-StatusLineNC

StatusLineNC	Status lines of not-current windows.
		Note: If this is equal to "StatusLine", Vim will use "^^^" in
		the status line of the current window.

Thanks for the insight!
