Different weights (regular, thin, bold etc.) of a font appear as a separate font

Hi, I'm not seeing an option to change the weight/style (regular, bold, extra bold, thin etc.) of fonts that have multiple weights in PowerPoint for office 365. I've seen a user having option to change the font weight/style on the right side of font.

No, I've seen a user using a font with multiple weights (regular, thin, extra bold etc.) like that it is showing as one font with a dropdown next to the font containing all these weights, rather than each weight of the font showing as a separate font.
