'Font adds a shade to the letter "W" when made it bold

I am using "FivoSans" font in my website and spotted a strange behaviour of the font when the added some font-weight to the font.

The font "FivoSans" is a font that I received from the client. And I added the font to the site using below code.

/* Fontface Imports */
@font-face {
    font-family: "FivoSans";
    src: url(/content/theme/fonts/FivoSans/FivoSans- Regular.otf) format("opentype");
}

The letter "W" has a little shade (or does not gets the font-weight added properly) when font-weight goes above 400.

enter image description here

Notice the letter "W" in News.

Following is the capture of inspect element in Google Chrome. enter image description here

Is there a way to fix this and does anyone have an idea why this is happening?
