IXO22 Really a 32Bit interface, not 24Bit?

I’ve just got a IXO22 as an emergency backup interface, as my main interface has just died on me (mid-project) and was very confused to see that the Mac shows it to be a 32Bit interface, not 24Bit as stated in all the marketing. I’ve attached some grabs to show this.

I truly don’t understand why - if it is a 32Bit interface - it would be mis-marketed as a 24Bit interface, as Steinberg would be rather underselling its abilities IMHO! With the current 40% off making it around £83 to £89 in the UK, it’s the bargain of the year!

32bit doesn’t mean anything in this case.
It’s not 32bit floating point. That’s a different story.
