Hello @ilyapokrov
I understand your concern but there’s nothing “incorrect” to be solved in the plugin. The plugin is loading fonts that your theme declares in CSS to be used but doesn’t load. Basically, it’s theme issue – theme is trying to use fonts that it doesn’t make available at the same time.
It’s a coincidence that Hustle actually loads those missing fonts but “technically speaking” Hustle is actually… “fixing” (coincidentally) your theme.
Let’s say that you want one wall in your office to be painted green and one to be painted red but you only bought green paint and forgot about red one. So you got plan when it says “this wall should be green and this one should be red” but only one is painted – the green one. Then your associate comes to the office, sees the plan and happens to have red paint at hand so paints that other wall red.
This is exactly what’s happening here but with fonts used on site instead – your theme “wants” to use specific font but it “forgot to load it” and then Hustle comes and “happens to have this missing font at hand” so it gets applied by the browser.
Kind regards,
Adam
