Perhaps they used the regular version, and forced italic in their software...
It was an error, sorry.
I finally didn't validate it because this font has some spacing problems (for example on the default preview with its name, big gap between B/a... and it would need some kerning between r/b)
Don't hesitate to reupload it if you can fix it
