Open Sans Italic missing and ExtraBold Italic mislabeled

Open Sans Italic is missing and Open Sans ExtraBold Italic is named as though it is the regular italic

Windows 11 Home ver. 10.0.22000
FontBase 2.17.5

I wonder why you get the 4 font styles to view. I see in this case the regular and regular italic styles because my open sans from Google fonts is a variable font. Fontbase doesn’t show the different weights of variable fonts. if I switch to the waterfall preview window I see the slider for the font weight preview …

Hello @apokaliptis, thank you for the post, welcome to the forum and sorry for the delay.
It looks like font designers made some errors while encoding font data in this case.
Thank you again.
